Methods for preparation of keratin fiber color coatings with a silicone aza michael composition

ABSTRACT

The methods and compositions of the present invention are directed to coloration of anagenic hair. The methods involve priming and deep cleaning the anagenic hair followed by coating the hair strands with a composite pigment containing film of a small molecule and a film forming composition which covalently interact to form an intimate three dimensional silicone network incorporating the pigment on the surfaces of the hair.

BACKGROUND

The recent two decades have seen significant effort directed toward development of external hair coloring technology that can be characterized as permanent but avoids bleach and penetration of dye precursors into the keratin fiber cortex. This technology in the main involves production of coloration of hair strands without involving the cortex. Hair coloration can be achieved by coating the surfaces of keratin fibers with a cosmetically acceptable polymer film containing pigment particles or with multi-layer polar attractive films containing coloration dyes instead of pigments. Numerous difficulties have plagued non-cortex hair coloration, however. Water soluble polymer films are easily removed by shampoo. Water insoluble and multi-layer films seem to have better remanence but they also typically survive only two or three shampoo washings. Film inflexibility, film irregularity, film thickness, inability to distribute color appropriately throughout hair tresses, film weakness and film dissolution through solvation, polar and/or ionic interaction with shampoo, organic liquids and other hair dressing components deliver undesirable tactile responses and physical displacement of the polymer film. These difficulties lead to flaking, hair strand breakage, artificial appearance, and irregular, undesirable color removal.

Hair coloring technology has made progress over the past five years in solving these issues. Color fading and development of elasticity of the color coating on the hair tresses have been achieved by various technologies. Additional improvements include development of techniques for combinations of various pigments and pigment distribution designed to mimic at least to some extent natural highlights of hair.

The kinds of coatings span a range of organic, silicone, organosilicone compositions to biological protein derivative compositions. Mixtures and layers of coatings are typical in this respect. Suitability and compatibility of such mixtures and layers and their interactions with hair and scalp are problematic. Failure to establish compatible inter-surface connections can lead to coatings exhibiting flaking, roughness, stiffness, irregular films, lack of flexibility, rough texture, touch and feel, and lack of remanence. Strong inner-coating and keratin fiber connections can lead to coatings that exhibit stiffness, flaking, thick texture/feel and extreme difficulty in attempts to remove and/or replace the coating with another coating. Rapid setting and lack of flowability of the compositions for application can lead to patchy coverage instead of contiguous coating formation.

When such coatings have been combined with keratin fibers such as hair, esthetically pleasing coloration with long remanence has proved impossible to achieve at present due to the intrinsic qualities of anagenic hair. To date, experimentation to develop keratin fiber coloration such as hair coloration has focused on the use of hair tresses or swatches. These tresses are formed of natural hair but are detached from source (a person) and are usually preprocessed to deliver ease of use for experimental purposes. Such tresses do not enable experimentation and exploitation of the issues and problems intrinsic with anagenic hair, i.e., hair growing from the scalp of a person. Anagenic hair differs from hair tresses because of hair root, mid-length and tip color differences of anagenic hair, keratin structural differences among and between root, mid and end portions of a living hair, continuous sebum secretions extending from the root to the end portion of each strand of anagenic hair, the individual differences in sebum compositional components from person to person, anagenic hair strand dimension, individualized topographic character of strand surfaces and keratin protein compositional differences from person to person, the fatty acid or F layer, the variation of curl and color of differing regions of anagenic hair on the scalp, scalp skin issues and environmental factors. Additional differences of anagenic hair relative to hair tresses include but are not limited to lack of cleanliness of anagenic hair, presence of pre-existing hair treatments including but not limited to hair styling formulations, permanent oxidative dye applications, permanent wave and/or curl treatment, application of oils and smoothing compositions and similar shampoo and conditioning treatments typically applied to anagenic hair. Still other difficulties involve regulatory requirements and the need to avoid tissue damaging and/or environmental attack by sunlight, UV, wind, rain and airborne chemicals, degrading chemicals in water and in hair care and hair dye compositions, as well as sweat and sebum.

Achievement of a truly successful hair coloration technology focuses on experimentation designed to address these problems and issues intrinsic with anagenic hair. While coatings with pigments provide a good starting point, connection of this technology to anagenic hair has yet to be achieved because of these intrinsic problems and issues. Hair coloration technology has demonstrated remanence and a modicum of natural coloration when applied to tresses. Nevertheless, this technology has failed to demonstrate success when transferred from tresses to anagenic hair.

SUMMARY OF THE INVENTION

These and other difficulties are addressed by aspects of the present invention. The present invention meets these objectives through the design and application methods to enable development of coloration of keratinous fibers such as but not limited to hair tresses, hair tresses designed to mimic anagenic hair, anagenic hair, eyebrow hair and eyelash hair, more preferably anagenic hair. The design and application of the methods of the invention feature several embodiments including pretreatment methods, film forming composition methods, deep cleaning methods, adjustment of components of each of the methods and control of parameters, conditions and additives for the methods. These multiple design features enable ready methods for application of the compositions to be dressed onto keratin fibers, preferably anagenic hair.

These multiple design features enable achievement of contiguous coating formation under processing parameters that enable unhurried dressing but rapid coating formation when desired. These multiple design features enable robust remanence, long wear-fastness, pleasing texture qualities, uniform color distribution and/or varied color distribution as well as establishing triggers for color coating removal. These multiple design features enable solution of “downstream problems” that can otherwise be associated with anagenic hair. Such downstream problems include but are not limited to development of strong but flexible interconnection between and among coating, pigment and hair strand surfaces, sebum and F layer effects upon such coating interconnections, root idiosyncrasies affecting interaction between color coating and keratin fiber surfaces, the effect of incomplete or ineffective removal of grubbiness, dirtiness, foulness of anagenic hair. In addition, the multiple design features of color coatings benefit the color arrangement, distribution and maintenance of the color of anagenic hair as it is assailed by environmental factors including but not limited to UV rays, shampoo, brushing, combing, rinsing, rain, wind, coverings by scarves and hats, rubbing and drying with towels and hair dryers, hair conditioners, styling hair sprays, hot iron curling and other environmental and hair care factors. At the same time, these multiple design features according to the invention provide tactile, visual, sound and olfactory sensations at least similar to untreated anagenic hair. According to the invention, the design features provide color coatings on keratin fibers, preferably anagenic hair, that deliver texture/tactile properties such as lightness, fluffiness, free flowing, silkiness, non-stickiness and non-matting and other physical interactions to colored keratin fibers, preferably colored anagenic hair, that are similar to the interactions of natural, non-colored keratin fibers, preferably anagenic hair of humans.

These and other aspects of the present invention include but are not limited to embodiments of methods for obtaining color coating of keratin fibers, preferably anagenic hair, embodiments of the color composition and the components thereof, and embodiments associated with methods for treatment of anagenic hair with embodiments of color compositions to form embodiments of color coatings of keratin fibers, preferably anagenic hair. These aspects additionally include qualities of the color coatings that deliver the above-described characteristics for hair coloration on keratin fibers.

An aspect of the invention utilizes inventive embodiments of the color composition and their components to produce embodiments of the color coating on keratin fibers, preferably anagenic hair. The color coating embodiments are produced by curing the color composition embodiments present on the keratin fibers. The color composition is an uncured combination of its components which may be cured to provide the color coating. Embodiments of these components comprise a pretreatment composition and a film forming composition. Embodiments of the pretreatment composition and film forming composition may be applied separately or together to the keratin fibers and converted (e.g., interbonded) according to methods of the invention to produce the color coating of an interconnected, overlapping and/or intermixed film laid onto keratin fibers such as surfaces of anagenic hair strands. The colored coating on the keratin fibers, preferably on anagenic hair, displays desirable characteristics including but not limited to remanence, wash-fastness, resistance to environmental attack. For keratin fibers, preferably anagenic hair, the colored coating delivers elastomeric flexibility to enable free movement of the coated keratin fibers, pleasing texture characteristics similar to uncoated hair, tensile strength to resist flaking and breakage, and color mimicking of appropriate shades for roots, mid-length and tips of keratin fibers.

An aspect of the invention directed to achievement of the color coating on keratin fibers concerns embodiments of the pretreatment composition applied according to method of the invention. Embodiments of the pretreatment composition comprise an organosilicon small molecule with alkoxysilyl groups and/or organoamine groups.

Another aspect of the invention directed to achievement of the color coating on keratin fibers concerns embodiments of the film forming composition applied according to the methods of the invention. Embodiments of the film forming composition comprise a binder comprising at least one linear silicone polymer binder having pendant and/or terminal α, β-unsaturated alkenoyloxy groups and a linker comprising a linear silicone polymer having pendant and/or terminal organoamine groups and optional terminal alkoxysilyl groups. These embodiments also comprise one or more microparticle pigments and color bodies. The embodiments of the film forming composition further may comprise at least a substance that functions as an ancillary component for promotion and/or improvement of such characteristics as one or more of coating leveling, promotion of curing, plasticization and flexibility, UV protection, pigment innerconnection with binder and/or linker and similar additive characteristics.

According to embodiments of the methods of the invention, embodiments of the pretreatment composition are applied to keratin fibers before and/or simultaneous with and/or in combination with application of the film forming composition to the keratin fibers. In some instances, the pretreatment composition may be applied and processed at least partially to facilitate condensation-cure of some of the alkoxy silyl groups before application of the film forming composition. In other instances, the film forming composition may be applied immediately after application of the pretreatment composition. In still other instances, the pretreatment composition and film forming composition may be combined together and applied as a mixture to the keratin fibers. Irrespective of the order of addition, the combined pretreatment and film forming compositions may be cured to effect the aza-Michael addition and to effect the alkoxysilyl condensation of the pretreatment composition and the optional condensation of the optional alkoxysilyl groups of the film forming composition with themselves and with the pretreatment composition. Although it is not a limitation of the invention, it is believed that irrespective of the order of addition, the pretreatment composition distributes preferentially to the keratin fiber surfaces so as to enable its interaction with features of the keratin protein at the surfaces of the keratin fibers.

Some aspects of the embodiments of the invention include at least in part a three-dimensional network of the color coating formed through the aza-Michael addition and alkoxysilane condensation of the color composition components comprising the film forming composition and pretreatment composition. Although it is not a limitation of the invention, it is believed that the initial small molecular size of the components of the pretreatment composition enable intimate networking interaction with keratin fiber surfaces and enable networking interaction with the components of the film forming composition so that the presence of incidental sebum of anagenic hair and subsequent sebum secretion onto anagenic hair do not at least in part remove the color coating from the anagenic hair surfaces.

Yet another aspect of the invention directed to achievement of the color coating on keratin fibers, especially on anagenic hair, concerns embodiments of the priming and/or deep cleaning of the surfaces of the keratin fibers. These embodiments are developed through practice of Praeparatur and Fundamenta techniques. These techniques deal with unique issues of anagenic hair such as but not limited to sebum coating on the keratin fiber strand surfaces, bound fatty acid layer (F layer) attached to keratin fiber strand surfaces, grime, grit, foulness and deposits from hair formulations previously applied to anagenic hair. The Praeparatur technique substantially to essentially primes the hair to remove surface crusting and/or glazing while the Fundamenta technique deep cleans the surface character and/or surface structure of keratin fibers as well as removes the F layer. These techniques may be applied separately and individually or may be applied together in either sequence. Irrespective of use of both or use of one or the other, these techniques are applied to hair before applying the pretreatment and film forming compositions. It is believed that the combination of one or more of the Praeparatur/Fundamenta techniques coupled with the pretreatment small molecule forming a network intimately adhering to the contours of the treated topographic surfaces of keratin fibers and the adherence among and between the small molecule network and the film forming composition produce a highly remanent color coating on anagenic hair.

Embodiments of the Praeparatur technique include but are not limited to mild agitation with a surfactant composition to strong interaction with an aqueous or aqueous organic or organic medium with anionic surfactant and/or rinsing with aqueous media optionally having pH adjustment. Additional procedures include optional mechanical agitation with such surfactant media and combing, brushing, vibrating, ultrasound and similar vibratory action applied to the surfaces of keratin fibers.

Embodiments of the Fundamenta method involve restructuring of the hair strand surfaces including F layer removal and include but are not limited to one or more of a non-thermal equilibrium plasma treatment; chemical treatment with phase transfer tenside such as but not limited to a fatty multi-alkyl ammonium halide; chemical treatment with aqueous or aqueous-organic oxidative medium such as ozone, persulfate or peroxide with optional alkali and optional surfactant cleaning.

Aspects of the invention are directed to embodiments of methods for application of the pretreatment composition, the film forming composition, and Praeparatur and Fundamenta techniques to form a color coating on keratin fibers such as anagenic hair. Embodiments of the methods comprise parameters, conditions and techniques for any one or more of: a) an application of the pretreatment composition to keratin fibers, preferably anagenic hair; b) an application of the film forming composition to keratin fibers, preferably anagenic hair; c) Praeparatur techniques applied to keratin fibers, preferably anagenic hair; and d) Fundamenta techniques applied to keratin fibers, preferably anagenic hair or any combination of these methods to form a color coating on keratin fibers, preferably anagenic hair.

The methods of the invention involving parameters, conditions and techniques for application of film forming composition may be directed to application of the film forming composition alone to keratin fibers. However, it is preferred that the methods of the invention involve parameters, conditions and techniques for application of the pretreatment composition to keratin fibers, preferably anagenic hair before, or simultaneous with, or mixed with, or in combination with the application of film forming composition. Additionally, application of sequential and/or simultaneous and/or mixed combinations of the pretreatment composition and the film forming composition may call for prior application of Praeparatur and/or Fundamenta techniques to keratin fibers, preferably anagenic hair.

According to the invention, the desirable characteristics of the color coatings on keratin fibers, preferably anagenic hair, may be demonstrated by tests of the coloration on hair tresses prepared from unbleached natural white human hair (hereinafter untreated hair tresses), bleached natural white human hair (hereinafter treated hair tresses) and untreated hair tresses specially prepared with sebum so as to mimic anagenic hair (hereinafter mimic hair tresses). The two base line forms of hair tresses (untreated and treated hair tresses) are not anagenic hair in that they are cut natural hair so that they are not bathed in sebum secretion but nevertheless have the F layer coating. The untreated hair tresses are substantially hydrophobic, have low porosity and have little or no keratin protein surface disruption. The treated hair tresses are substantially less hydrophobic to more hydrophilic than, and have greater porosity than, the untreated hair tresses. The treated hair tresses also display low to mild keratin protein surface disruption. The mimic hair tresses are especially treated to demonstrate the sebum, F layer, grubbiness, foulness, and root, mid-length and tip issues associated with anagenic hair and especially those associated with the root segment of anagenic hair. The root segment of anagenic hair is constantly bathed in sebum and has the F layer coating so that the root segment of anagenic hair shows the most extreme behavior difference relative to treated and untreated hair tresses. To establish the mimicry, the untreated hair tresses undergo a series of preparations designed to establish a close comparison with the behavior of anagenic hair especially the root segments. To this end, embodiments of color coatings according to the invention have been studied with anagenic hair, untreated hair tresses, treated hair tresses. The results of these preliminary studies have established the techniques and components for development of these hair tresses to enable their similarity to the behavior of anagenic hair, especially the root segments of anagenic hair. Untreated, treated, and mimic hair tresses are accordingly able to function as the substrates for experimental development of the embodiments of the color coatings and methods for hair coloration with anagenic hair.

When color coatings are formed onto untreated and onto treated tresses, long lasting remanence is exhibited. However, when the same color coatings are applied to anagenic hair such as the hair of a live salon hair model, remanence disappears. For efficiency of experimental practice, the above described mimic hair tress has been developed to come as close as possible to the behavior of anagenic hair, especially the root segments of anagenic hair. Through use of the mimic hair tress, it has been surprisingly discovered that the combination of the Praeparatur and Fundamenta techniques and the small molecule pretreatment network coupled with the aza-Michael binder preserve remanence for color coatings on mimic hair whereas those color coatings on mimic hair prepared without application of the Praeparatur and/or Fundamenta techniques demonstrate significant to almost full fading during the multiple shampoo applications designed to examine remanence in real life conditions.

DEFINITIONS

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by a person of ordinary skill in the art.

As used in the specification and the appended claims, the singular forms “a,” “an” and “the” include plural referents unless the context clearly dictates otherwise.

The term “may” in the context of this application means “is permitted to” or “is able to” and is a synonym for the term “can.” The term “may” as used herein does not mean possibility or chance.

The term and/or in the context of this application means one or the other or both. For example, an aqueous solution of A and/or B means an aqueous solution of A alone, an aqueous solution of B alone and an aqueous solution of a combination of A and B.

The molecular weight of a polymer or oligomer used according to the invention may be measured by a weight average molecular weight, and the distribution of molecules of different molecular weights of a polymer or oligomer used according to the invention is determined by its polydispersity. Molecular weight is expressed as daltons (Da), kiloDaltons (KDa) and megaDaltons, which is million daltons or (MDa). The acronym M_(W) stands for weight average molecular weight, M_(n) is the number average molecular weight of a given polymer. Polydispersity is a unit-less number and indicates the breadth of the distribution of the polymer molecular weights and is defined as the M_(w)/M_(n).

The term “about” is understood to mean±10 percent of the recited number, numbers or range of numbers.

The term “about 0 wt %” is understood to mean that no substance, compound or material to which zero (0) refers is present, up to a negligible but detectable amount is present, assuming that the detectability can be determined on a parts per million basis.

Where features or aspects of the invention are described in terms of Markush groups, those skilled in the art will recognize that the invention is also thereby described in terms of any individual member or subgroup of members of the Markush group. For example, if X is described as selected from the group consisting of methyl, ethyl or propyl, claims for X being methyl and claims for X being methyl and X being propyl are fully described. Moreover, where features or aspects of the invention are described in terms of Markush groups, those skilled in the art will recognize that the invention is also thereby described in terms of any combination of individual members or subgroups of members of Markush groups. Thus, for example, if X is described as selected from the group consisting of bromine, chlorine, and iodine, and Y is described as selected from the group consisting of methyl, ethyl, and propyl, claims for X being bromine and Y being methyl are fully described.

If a value of a variable that is necessarily an integer, e.g., the number of carbon atoms in an alkyl group or the number of substituents on a ring, is described as a range, e.g., 0-4, what is meant is that the value can be any integer between 0 and 4 inclusive, i.e., 0, 1, 2, 3, or 4. Similarly, values expressed in a range format should be interpreted in a flexible manner to include not only the numerical values explicitly recited as the limits of the range, but also to include all the individual numerical values or sub-ranges encompassed within that range as if each numerical value and sub-range were explicitly recited. For example, a range of “about 0.1% to about 5%” or “about 0.1% to 5%” should be interpreted to include not just about 0.1% to about 5%, but also the individual values (e.g., 1%, 2%, 3%, and 4%) and the sub-ranges (e.g., 0.1% to 0.5%, 1.1% to 2.2%, 3.3% to 4.4%) within the indicated range.

Keratin fibers means any natural keratin material containing keratin protein including hair, eye brows and eyelashes. Natural keratin fibers include those from mammals and/or on mammals including human, primate, ruminant, camelid, equine, rodent and neovison including but not limited to cow, sheep, deer, goat, buffalo, lama, alpaca, camel, guanaco, vicuna, horse, antelope, moose, elk, rat, mouse, beaver, rabbit, mink, monkey, ape and similar species. Natural keratin material may include hair and fur. Keratin fibers include scalp hair, eyebrow hair and eyelash hair. Keratin fibers may be removed from their source such as hair cut from the scalp of a living person or may mimic anagenic hair when treated with sebum. As used herein keratin fibers includes cut hair, mimic hair tresses and anagenic hair. For experimental purposes, keratin fibers are formed into tresses. A tress is a shock of keratin fibers e.g., hair, held in a clamp at one end and free at the other end. The hair on the head of the average person weighs about 100 g. A tress is formed with about 1 gram of hair or about 1/100 the weight of the hair on the head of a person. Typical commercial hair products for application to hair weigh about 100 to 120 g which translates into about 1 g of product per gram of a person's hair. This relationship establishes the amount of experimental product to be applied to a tress of hair, 1 gm of experimental product per tress weighing about 1 g.

As used herein “anagenic hair” means hair strands that are in direct connection with a hair follicle which is in either the anagen or telogen state. Anagenic hair is present in one of these states on a scalp of a person, a human. The follicle of anagenic hair produces long chain fatty acids, so-called F-layer, which form a water resistant coating on the cuticle of the hair shaft. Joining the hair follicle channel is a sebaceous gland that secretes sebum onto the hair shaft and onto the scalp. As a strand of hair grows from the follicle and extends from the scalp, sebum produced at the follicle spreads out from the follicle and continues to coat the strand. Sebum is removed at least in part from strand ends by shampooing but is replenished by this continued production. Hair cut from a living person is no longer anagenic hair.

As used herein, the terms “covalent, coordinate, electrostatic, ionic, dipolar and entanglement or entwining interactions” mean a chemical relationship between two atoms or two groups of atoms. The interaction includes a covalent bond between the atoms such as the covalent bond between the two carbons of ethane. The interaction includes a coordinate bond between two or more atoms such as the coordinate bond between oxygen and sulfur of the sulfate anion (SO₄ ⁻²) or a complex of zinc and EDTA. The interaction includes an electrostatic or ionic interaction between two charged atoms or particles such as the interaction between sodium and chloride of salt or between ammonium and acetate of ammonium acetate. Dipolar interaction includes hydrogen bonding such as the interaction between water and the hydroxyl of methyl alcohol. The interaction includes entanglement or entwining which is lipophilic interaction or mechanical/physical twisting together such as is present in the molecules of polyethylene.

Adherence as used herein generally refers to an arrangement in which a substance formed of a polymer, oligomer or small molecule exhibits a connective aspect with another material such as another polymer, oligomer, small molecule, keratin protein, through such forces as covalent bonding, hydrogen bonding, coordinate interaction, electrostatic interaction, dipolar interaction, small force interaction, dispersion force at least as a result of entropy, molecular entanglement, mechanical interaction as may be exhibited on a molecular level by a molecular chain wrapping around irregular terrain features of a surface. Adherence in this context may be, but not necessarily, shown by the inability of the adhered material to be removed from the substance without exertion of any force.

Entanglement as used herein generally refers to an arrangement in which a chain crosses an arbitrary plane 3 times. The chain is then entangled. If the chain is shorter and crossed only two times, it can be pulled in the middle and both ends will release without being bound. With three crossings, if the chain is at one point, it will trap another polymer chain at a different place.

As used herein, the term “transfer resistance” or rub off resistance generally refers to the quality exhibited by colored coatings that are not readily removed by contact with another material, such as, for example, an item of clothing or the skin. Transfer resistance can be evaluated by any method known in the art for evaluating such transfer. For example, transfer resistance of a colored coating can be evaluated by the amount transferred from a wearer to any other substrate after the expiration of a certain amount of time following application of the colored coating to the hair. The amount of colored coating transferred to the substrate can then be evaluated and compared. For example, a colored coating can be transfer resistant if a majority is left on the wearer's hair. Preferably little or no colored coating is transferred to the substrate from the hair.

As used herein, the term “minimally alters the keratin fibers, upon application” generally means that after removal of the composition coating on the keratin fibers, the keratin fibers are returned to a substantially unaltered state. The state of the keratin fibers can be assessed for example using ATR FT-IR for oxidative damage as described later or through tensile testing methods known to those skilled in the art for assessing fiber strength for example using equipment such as those designed and sold by Dia-Stron™.

As used herein, the term “converting” means causing covalently co-reactive pairs of components of a composition such as but not limited to the binder and linker of the film forming composition to react together chemically to produce the reacted form such as, for example a chain-extended and/or cross linked polymer functioning as coating or film. Converting is accomplished by the application of an activity designed to cause the covalent bonding of the reactive groups or pairs of the co-reactive components. Activities enabling conversion include but are not limited to one or more of drying, heating, curing as in causing the curing/reacting together the co-reactive components, allowing the co-reactive components to combine or mix at standard conditions without further intervention, addition of a catalyst, changing pH of the composition and any other activity that is capable of influencing the reactivity and/or rate of the reaction of the co-reactive components.

“Aliphatic substituent, group or component” refers to any organic group that is non-aromatic. Included are acyclic and cyclic organic compounds composed of carbon, hydrogen and optionally of oxygen, nitrogen, sulfur and other heteroatoms. This term encompasses all of the following organic groups except the following defined aromatic and heteroaromatic groups. Examples of such groups include but are not limited to alkyl, alkenyl, alkynyl, corresponding groups with heteroatoms, cyclic analogs, heterocyclic analogs, branched, dendritic, star or fullerene-like and linear versions and such groups optionally substituted with functional groups, as these groups and others meeting this definition of “aliphatic” are defined below.

“Aromatic substituent, group or component” refers to any and all aromatic groups including but not limited to aryl, aralkyl, heteroalkylaryl, heteroalkylheteroaryl and heteroaryl groups including multiple forms thereof. The term “aromatic” is general in that it encompasses all compounds containing aryl groups optionally substituted with functional groups (all carbon aromatic groups) and all compounds containing heteroaryl groups optionally substituted with functional groups (carbon-heteroatom aromatic groups), as these groups and others meeting this definition of “aromatic” are defined below.

As used herein, the term “optionally” means that the corresponding substituent or thing may or may not be present. It includes both possibilities.

“Alkyl” refers to a straight or branched, dendritic, star or fullerene-like or cyclic hydrocarbon chain group consisting solely of carbon and hydrogen atoms, unless otherwise specifically described as having additional heteroatoms or heterogroups. The alkyl group contains no unsaturation, having from one to twenty four carbon atoms (e.g., C₁-C₂₄ alkyl). Whenever it appears herein, a numerical range such as for example but not limited to “1 to 24” refers to each integer in the given range; e.g., “1 to 24 carbon atoms” means that the alkyl group may consist of 1 carbon atom, 2 carbon atoms, 3 carbon atoms, etc., up to and including 24 carbon atoms, although the present definition also covers the occurrence of the term “alkyl” where no numerical range is designated. In some embodiments, it is a C₁-C₄ alkyl group. In other instances, it is a C₁-C₆ alkyl group and in still other instances it is a C₁-C₂₄ alkyl group. Typical alkyl groups include, but are in no way limited to, methyl, ethyl, propyl, isopropyl, n-butyl, iso-butyl, sec-butyl isobutyl, tertiary butyl, pentyl, isopentyl, neopentyl, hexyl, septyl, octyl, nonyl, decyl, and the like. The alkyl is attached to the rest of the molecule by a single bond, for example, methyl (Me), ethyl (Et), n-propyl, 1-methylethyl (iso-propyl), n-butyl, n-pentyl, 1,1-dimethylethyl (t-butyl), 3-methylhexyl, 2-methylhexyl, and the like.

“Alkylenyl” refers to a straight or branched, dendritic or star divalent hydrocarbon chain consisting solely of carbon and hydrogen atoms, unless otherwise specifically described as having additional heteroatoms or heterogroups. The alkylenyl group contains no unsaturation, has a dangling valence bond at either end of the chain for bonding to two other moieties. The alkylenyl group may have a carbon number range of 1 to 24 carbon atoms unless otherwise specified. In all cases the general and specific numerical range of carbon atoms includes each integer in the range. An example of a divalent hydrocarbon chain designated as an alkylenyl group is as follows: —CH₂—CH₂—CH₂—CH₂—; the dashes (-) indicate valence bonds to other atoms or moieties not shown. This example of an alkylenyl group is butylenyl.

“Cycloalkyl” is a subcategory of “alkyl” and refers to a monocyclic or polycyclic group that contains only carbon and hydrogen, and may be saturated, or partially unsaturated. Cycloalkyl groups include groups having from 3 to 24 ring atoms (i.e., C₃-C₂₄ cycloalkyl). Whenever it appears herein, a numerical range such as but not limited to “3 to 24” refers to each integer in the given range; e.g., “3 to 24 carbon atoms” means that the cycloalkyl group may consist of 3 carbon atoms, etc., up to and including 24 carbon atoms. In some embodiments, it is a C₃-C₈ cycloalkyl group. In some embodiments, it is a C₃-C₅ cycloalkyl group. Pursuant to the definition of alkylenyl, a cycloalkyenyl group is a monocyclic or polycyclic group with two dangling valences for bonding to two other moieties. Illustrative examples of cycloalkyl groups include but are not limited to the following moieties: cyclopropyl, cyclobutyl, cyclopentyl, cyclopentenyl, cyclohexyl, cyclohexenyl, cycloseptyl, cyclooctyl, cyclononyl, cyclodecyl, norbornyl, and the like.

“Alkoxy” refers to the group —O-alkyl, including from 1 to 24 carbon atoms of a straight, branched, dendritic, star or cyclic configuration and combinations thereof attached to the parent structure through an oxygen. Examples include methoxy, ethoxy, propoxy, isopropoxy, cyclopropyloxy, cyclohexyloxy and the like. “Lower alkoxy” refers to alkoxy groups containing one to six carbons. In some embodiments, alkyl is an alkyl group which encompasses both straight and branched, dendritic, star or fullerene-like chain alkyls. Without further definition of the number or carbon atoms present, as used herein, the term “alkoxy” such as an alkoxysilyl group means a C₁-C6, preferably C₁-C₄, more preferably C₁-C₂ alkoxy such as methoxy and ethoxy.

The term “alkoxysilyl” refers to a siloxane moiety substituted by three alkoxy groups, in other words a trialkoxysilyl group, and in which the silicon atom joins either a carbon or an oxygen depending upon the identity of the moiety to which the alkoxysilyl group is bound, such as but not limited to an organic compound, a siloxane compound, an organosiloxane compound, an organic polymer backbone, a silicone polymer backbone or an organosilicone backbone. Thus, the term “alkoxysilyl” as used herein is a synonym and means a trialkoxysilyl group, in other words —Si(OR)₃ in which R is an alkyl group of 1 to 6 carbons, preferably 1 to 3 carbons and more preferably methyl or ethyl. Also, because the hydrolysis intermediate of each alkoxy of the alkoxysilyl group is hydroxy group as in hydroxysilyl, the hydroxysilyl group is included in this definition. One of the alkoxys of the alkoxysilyl group may hydrolyze and the resulting hydroxysilyl may condense with another hydroxysilyl group derived from the corresponding alkoxysilyl group to form an Si—O—Si bond. Because there are three alkoxy groups on this moiety, the formation of a silicon-oxygen-silicon bond may occur as many as three times for a single alkoxysilyl (trialkoxysilyl) group. Irrespective of whether the alkoxysilyl group is pendant or terminal on a molecule such as a small molecule, oligomer or polymer, this multiple Si—O—Si bonding arrangement for a single alkoxysilyl group means that the molecule with the single alkoxysilyl group may undergo multiple condensations. The molecule with an alkoxysilyl may be chain extended with another molecule with an alkoxysilyl to produce a linear chain extended molecule. This linear chain extended molecule contains additional Si—OR functions at this Si—O—Si chain extension. These additional Si—OR functions can again condense with a corresponding Si—OR function of another linear chain extended molecule. The result is a cross-link at the intermediate section of these molecules bearing the Si—O—Si link. These additional Si—OR's of separate chain extended molecules can therefor condense to cross link the separate chain extended molecules.

Hydrogen bonding refers to a weak bond between two molecules resulting from an electrostatic attraction between a proton in one molecule and an electronegative atom in the other. Ionic bonding refers to a type of chemical bonding that involves the electrostatic attraction between oppositely charged ions.

Young's modulus, or the Young modulus, is a mechanical property that measures the stiffness (e.g., stretchiness) of a solid material. It defines the relationship between stress (force per unit area) and strain (proportional deformation) in a material in the linear Hookean elastic regime of a uniaxial deformation. In other words, the ability of a material to withstand changes in length when under lengthwise tension or compression.

The term Tg or glass transition temperature refers to the temperature range through which a material, such as but not limited to a polymer, transitions from amorphous solid-like or glass-like properties at a lower temperature to viscous or rubber-like properties at a higher temperature. The transition is not a phase transition such as solid to liquid. Embodiments of the color coatings on mimic hair, treated hair and untreated hair typically will exhibit a Tg range well below ambient temperature so that the films produced will exhibit flexible, elastomeric, smooth physical properties.

The term ultimate compression refers to the amount of compression a given material can experience under a specific test method before failure occurs and the material breaks.

A nanoemulsion is a liquid/liquid, liquid/solid, liquid/gas or gas/gas composition in which there is at least one discontinuous phase dispersed in a continuous phase and in which the average particle or micellar diameter of the discontinuous phase is in the range 10 nm-300 nm.

The term “sebum” is an oily, waxy substance produced by the sebaceous glands of the human body. It coats, moisturizes, and protects skin and hair. Sebum is primarily composed of triglycerides (≈41%), wax esters (≈26%), squalene (≈12%), and free fatty acids (≈16%). The sebum used to form mimic hair is a Hautfett nach BEY, sold by Wfk-Testgewebe GmbH which comprises 18.0% free fatty acids, 32.8% beef tallow, 3.6% triglycerides, 18.3% wool fat, 3.7% cholesterol, 12.0% hydrocarbons, 11.6% cutina.

The term “surface energy” quantifies the disruption of intermolecular bonds that occurs when a surface is created. The surface energy may be defined as the excess energy at the surface of a material compared to the bulk, or it is the work required to build an area of a particular surface. Perhaps the most widely used definition of surface energy, historically, is that of Zisman (“Relation of Equilibrium Contact Angle to Liquid and Solid Constitution”, W. A. Zisman, ACS Advances in Chemistry Series #43, 1961, pp. 1-51.). Zisman defines the surface energy of a solid to be equal to the surface tension of the highest surface tension liquid (real or imaginary) that will completely wet the solid, with a contact angle of 0°. This comes from the widely observed tendency of contact angle to decrease as liquid surface tension decreases on the same solid sample. A Zisman plot is created for a test surface using a series of different probe liquids with known surface tensions, with the known surface tensions plotted on the x axis, and the cosine of the resulting contact angle with the test surface plotted on the y axis. The highest surface tension when the cosine of the contact angle reaches 1 is determined to be the surface energy of the test substrate. The Owens/Wendt theory (Owens, D. K.; Wendt, R. C.; Jour. of Applied Polymer Science, 13, 1741, (1969)) is a further development to measure the surface energy of a test substrate. It considers the surface energy being comprised of two components—a dispersive component and a polar component. The dispersive component accounts for van der Waals and other non-site specific interactions that a surface is capable of having with applied liquids. The polar component theoretically accounts for dipole-dipole, dipole-induced dipole, hydrogen bonding, and other interactions which a surface is capable of having with applied liquids. Owens and Wendt developed a two parameter model for describing surface interactions, as opposed to the one parameter model of Zisman. The units of surface energy are mN m⁻¹.

The terms “priming” and “deep cleaning” refer to the substantial to essentially complete removal of sebum and F-layer substances from the surfaces of anagenic hair and also refer to removal of synthetic sebum and F layer substances on mimic hair tresses. The Praeparatur and Fundamenta techniques accomplish the priming and deep cleaning of keratin fiber surfaces. Practice of these techniques may accomplish adjustment of the keratin fiber surfaces so as to expose variable surface topography and gain an intimate interaction with agents small enough to access the variations of the topography.

DETAILED DESCRIPTION

The present invention is directed to methods and compositions for development of color coatings on keratin fibers, particularly anagenic hair. These methods and compositions may also be applied to keratin fibers relating to all sources such as hair tresses, animal hair and similar keratin fibers. The qualities and properties of the aspects of the pretreatment composition, the film forming composition, their combination as the color composition, the curing thereof, the Praeparatur and Fundamenta techniques and methods of application contribute to, enhance and promote qualities of the resulting color coating so that the coated keratin fibers and especially coated mimic tresses and anagenic hair demonstrate significant remanence while also demonstrating a performance similar to that of young, uncoated, vibrant, attractive hair of the scalp. To accomplish this aspect, the color coating exhibits qualities including but not limited to flex, stretch and bend, integrity of continuous film under flex, stretch and bend conditions, wash-fastness, remanence, color coordination and resistance to degradation and damage caused at least by, but not limited to, UV radiation, sebum, F layer, sweat, rain, wind and/or environmental attack.

The Method for Forming a Color Coating on Keratin Fibers

Embodiments of the method for forming the color coating on keratin fibers involve the steps of application of compositional embodiments to the surfaces of the keratin fibers to form a composite film on the surface followed by drying and curing the composite film to form the color coating on the surfaces of keratin fibers. The compositional embodiments include a pretreatment composition and a film forming composition. The pretreatment composition comprises a medium and an organosilicone small molecule with at least alkoxysilyl groups and/or organoamine groups. The film forming composition comprises a medium, a binder with α,β-unsaturated alkenoyloxy groups (Michael groups) and a linker with organoamine groups (aza groups). The film forming composition also comprises pigment microparticles and color bodies. The binder, linker and pigment/color body components of the film forming composition are maintained separately in media and are mixed prior to use. The pigment/color body component comprises groups of preformulated differently colored microparticle pigments/color bodies optionally coated with the organosilicone small molecule of the pretreatment composition dispersed in a dispersant medium. Selections from the groups of differently colored pigments may be pre-blended and provided as a wide number of choices of pre-formulated shades and hues for the hair to be colored. Alternatively, basic pigment formulas may be provided, custom blended and combined with the film forming composition just before use so as to provide the desired color shade and hue for the hair to be colored.

To prepare the keratin fibers, especially anagenic hair, for coloration, the keratin fibers are primed and deep cleaned with either, or both in any order, of the Praeparatur and Fundamenta techniques. As explained above, priming and deep cleaning combined with the pretreatment and film forming compositions delivers a color coating on anagenic hair that displays significant remanence.

The Film Forming Composition

Embodiments of the film forming composition are directed to multiple components comprising a binder and a linker that are adapted to combine in situ to crosslink through an Aza-Michael addition. The binder comprises a silicone polymer having pendant and/or terminal α,β-unsaturated alkenoyloxy groups. The linker comprises a silicone polymer having pendant and/or terminal organoamine groups and optional pendant and/or alkoxysilyl groups. Preferably, the binder and linker are linear and/or branched, more preferably linear. The film forming composition further comprises one or more microparticle pigments and/or color bodies. The film forming composition also comprises a medium in which the multiple components, pigment(s) and/or color bodies are dispersed, mixed and/or otherwise contained (color bodies being synonymous with pigments). The film forming composition may but not necessarily further comprise one or more ancillary components as adjuncts for helping and/or promoting characteristics of the color coating on keratin fibers. Application of the film forming composition to keratin fibers may also include a conversion step such as drying and curing to evaporate residual medium from the film forming composition on the surfaces of the keratin fibers and to cause the aza-Michael addition reaction thereby producing a chain extended, cross linked polymer network comprising a film.

The binder and linker components of the film forming composition are separately maintained until immediately prior to use. The film forming composition is prepared for use for application to keratin fibers by combining and mixing the binder and linker components in media according to the proportional quantities described below. The pigment/color bodies with dispersant may also be combined as described below to form the film forming composition with pigment/color bodies.

Binder

The binder may be a silicone polymer with at least two pendant and/or terminal α,β unsaturated alkenoyloxy groups, and preferably at least two of the α,β unsaturated alkenoyloxy groups are terminal groups. The binder may have a linear or branched, preferably a linear configuration.

In particular, embodiments of the binder of the film forming composition comprise a polydimethylsiloxane-type polymer having at least two or at least three α,β unsaturated alkenoyloxy groups attached to siloxane units of the polymer. The α,β-unsaturated alkenoyloxy groups comprise the Formula EOY:

R¹R²C═CR³COO—R⁴—   Formula EOY

In Formula EOY, each of R¹ and R² may independently be hydrogen or a C1-C6 linear or branched alkyl group. Preferably at least one of R¹ and R² is hydrogen. The group R³ may be hydrogen or methyl. The group R⁴ is a part of the connector group that joins Formula EOY to silicon of a siloxane unit of the polydimethylsiloxane-type silicone polymer. The group R⁴ may be a C1-C12 linear alkylenyl group, a linear C3-C12 cycloalkylalkyl or cycloalkyl group, a linear C6-C20 arylalkyl group or C6 to C20 aryl group wherein R⁴ may be optionally substituted in chain by one or more of an ether oxygen, thioether sulfur and/or amine groups or pendantly by hydroxyl groups. The group R⁴ is bonded directly with a silicon atom of a siloxane unit of the dimethylsilxane-type silicone polymer. A preferred embodiment of Formula EOY is H₂C═CR³COO—R⁴—, and a more preferred embodiment is H₂C═CHCOO—R⁴—.

Embodiments of the binder of the film forming composition may be linear and/or branched, preferably linear and comprise a silicone polymer constructed of D and M siloxane monomeric units. Branched forms may include T units (MeSiO₃) in the backbone which form branch junctions for branch chains carrying D and M units, however, linear forms are preferred. The binder silicone polymer comprises Formula I:

(X_(z))SiMe_(3-z)O-(Me₂SiO)_(x)—(XSiMeO)_(y)—(X_(z))SiOMe_(3-z)   Formula I

For Formula I, two or more of the D and/or M units are modified with X which is the α,β-unsaturated alkenoyloxy group of Formula EOY. Each of the siloxane units Me₂SiO and Si(X)MeO comprise monomeric siloxane D units with Me being methyl. The terminal units (X_(z))SiMe_(3-z) comprise monomeric siloxane M units. The designator z is zero or 1 so that the terminal units may have a single Formula EOY group or may be a trimethylsiloxane unit. The designator x primarily determines the molecular size of the silicone polymer binder and may range from about 2 to 200,000, preferably from about 5 to about 50,000, more preferably from about 5 to about 1,000. The designator y primarily determines the number of Formula EOY groups in the binder and may range from 0 to about 100, preferably about 2 to about 25, more preferably about 2 to about 20. The sum of designators y and z must at least be 1 and preferably 2 so that Formula I has at least one, preferably at least 2 Formula EOY groups. The designator x primarily determines the length of the linear silicone polymer and may integer range from about 3 to about 200,000, preferably up to about 500, more preferably up to about 200 with exemplary integer sums of up to about 100. The multiple monomeric units of Me₂SiO and (X)SiMeO are randomly distributed in Formula I.

Preferred embodiments of Formula I are those with designator y as zero and z as 1. These embodiments provide binders with terminal Formula EOY only. Additional preferred embodiments are those with designator x as at least 5, designator y as 1 to 5 and z as 1. These embodiments provide binders with terminal Formula EOY's and from 1 to 5 pendant Formula EOY's. Yet other especially preferred embodiments are those with designator x as at least 10, designator y as 2 to 6 and z as zero. These embodiment provide binders with 2 to 6 pendant Formula EOY's and no Formula EOY's as termini. Instead, the binder is terminated with Me₃SiO groups.

Another preferred embodiment of the foregoing preferred embodiments of Formula I has Formula EOY as H₂C═CR³COO—R⁴—. More preferred of these especially preferred embodiments of Formula I (Formula EOY with designations of R¹ and R² as hydrogen) are those in which R⁴ is a linear C2-C8 alkylenyl group and more especially preferably is the R⁴ group as —CH₂CHOH—CH₂—O—(CH₂)_(n)— wherein n is an integer of 1 to 6. Most especially preferably for all of these embodiments of Formula I has Formula EOY as H₂C═CR³COO—CH₂CHOH—CH₂—O—(CH₂)₃—

An especially preferred embodiment of the binder of Formula I is Formula IV:

H₂C═CHCOOCH₂CHOH—CH₂—O—(CH₂)_(c)—SiMe₂O—(SiMe₂O)_(m)-[MeSiO—(—(CH₂)_(c)—O—CH₂—CHOH—CH₂OOC—CH═CH₂)]_(g)-(Me₂SiO)_(p)—OSiMe₂-(CH₂)_(c)—O—CH₂—CHOHCH₂OOCCH═CH₂   Formula IV

This especially preferred embodiment of the binder provides Formula EOY as terminal groups and as pendant groups of the polydimethylsiloxane-type polymer. In this embodiment, designator c determines the length of the alkylenyloxo group connecting the α,β-unsaturated alkenoyloxy group to silicon of the polymer backbone. Designator c may be an integer of 1 to 6, preferably 3. The designators m and p establish the size or length of the linear silicone polymer and separate the pendant α,β-unsaturated alkenoyloxy groups from the terminal α,β-unsaturated alkenoyloxy groups. Designator m and p may each independently range from about 5 to about 100. Designator g establishes how many pendant α,β-unsaturated alkenoyloxy groups are present in this embodiment of the binder. Designator g may be zero which provides a Formula IV embodiment with no pendant α,β-unsaturated alkenoyloxy groups but with termini each with an α,β-unsaturated alkenoyloxy group. Designator g may alternatively be an integer of from 1 to about 10. In this embodiment, the —O—CH₂)_(c)-moiety connects Formula EOY to the silicone backbone as a carbon to silicon bond. To accomplish the joinder, a route through an alkenyl moiety may be followed. An alkenyloxoalkyl bromide may be combined with a silicon halide using an alkyl lithium or Grignard reagent to provide an Si-alkyloxoalkene moiety. The olefin bond of the alkene group may be epoxidized and the epoxy group combined with the α,β-unsaturated alkenoic acid such as acrylic acid to form Formula EOY.

Preferred embodiments of Formula IV include those with g as an integer of from 1 to 5 and c and c′ each as an integer of 1 to 3 and each of m and p as 10 to 50. This embodiment provides a binder with Formula EOY as the termini and as 1 to 5 pendant groups. Another preferred embodiment of Formula IV provides g and p as zero, and c and c′ as an integer of 1 to 3. This embodiment provides a binder with Formula EOY as termini only.

The M1 and M2 units constitute the termini of the silicone polymer as indicated. The D units form the backbone of the silicone polymer as indicated. Branched forms may include T units (MeSiO₃) in the backbone which form branch junctions for branch chains carrying D and M units, however, linear forms are preferred. The M1 and M2 units are selected from Me₃SiO units, A-SiMe₂O units in which A is an organoamine group and —SiOR₃ units (trialkoxysilyl units) in which R is ethyl or methyl. The D units are selected from SiMe₂O units and A-SiMeO units. For the D units, the designator d indicates the length of the linear silicone polymer and may range from 3 to 30,000, preferably 3 to 25,000, more preferably 2,000 to 10,000.

For the D and M units, the A moiety, an organoamine group, comprises Formula OA:

Preferred embodiments may be also selected to provide at least one D unit and one of the M1 and M2 units with Formula OA groups and the other of the M1 and M2 units as a trialkoxysilyl group. Preferred embodiments may also be selected to provide at least 2 D units with Formula OA groups and the M1 and M2 units both as trialkoxysilyl groups.

Especially preferred versions of these preceding preferred and more preferred embodiments may be selected to provide Formula OA groups only in D units and trialkoxysilyl groups as both of the M1 and M2 units.

Formula V as the preferably linear polydimethylsiloxane-type polymeric linker may be expanded to show the monomeric units possible. Accordingly, the linker is formed from the following list of monomeric units with the M and D designations shown below the list:

(Me₃SiO) (Si(OR)₃ (A-SiMe₂O) (SiMe₂O)_(o) (SiMeO-A)_(p) M-T1 M-T2 M-T3 D-B1 D-B2 The first three units form termini (M-T1-M-T2-M-T3) for the linker. The last two units form the backbone of the linker (D-B1-D-B2) with the majority of the backbone units being the dimethylsiloxane unit, D-B1. The designator o for the dimethylsiloxane unit is an integer of from 2 to 100. The designator p for the siloxane backbone groups carrying Formula OA may be zero or an integer of from 1 to 10. The symbol A stands for Formula OA described above. M-T3 and D-B2 carry the amine group Formula OA. Unit M-T2 is the trialkylsilyl group. As a terminus, silicon of the M-T2 unit is bound to oxygen of the adjacent D-B1 unit of the backbone of the dimethylsiloxane-type polymer forming the linker.

As described above, embodiments of the linker may be ordered according to the identity of the group as the termini. In all of these embodiments the silicone backbone primarily is the D-B1 unit. The number of D-B1 units in the backbone is calculated to provide the weight average molecular weight range of the linker as described below. These embodiments include but are not limited to:

-   -   A) Both termini as M-T1 (trimethylsiloxane) in which case the         backbone will carry at least one unit of the amine Formula OA as         D-B2, and preferably two or three D-B2 units.     -   B) One terminus as M-T1 and the other terminus as M-T2         (alkoxysilyl). In this case, the backbone will carry at least         one of the amine Formula OA as unit D-B2 and preferably two or         three D-B2 units.     -   C) One terminus as M-T1 and the other as M-T3 (M unit carrying         organoamine Formula OA) in which case the backbone will carry at         least one amine Formula OA as unit D-B2 and preferably two or         three D-B2 units.     -   D) One terminus as M-T2 (alkoxysilyl) and the other as M-T3 (M         unit carrying organoamine Formula OA) in which case the backbone         will carry at least one amine Formula OA as unit D-B2 and         preferably two or three D-B2 units.     -   E) Both termini as M-T2 (alkoxysilyl) in which case the backbone         will carry at least one amine Formula IA as unit D-B2 and         preferably two or three D-B2 units.     -   F) Both termini as M-T3 (M unit carrying organoamine Formula OA)         in which case the backbone may have no D-B2 units.     -   G) Both termini as M-T3 in which case the backbone may carry at         least one or two D-B2 units.

Embodiments of the binder of the film forming composition may have their designators chosen to indicate a number of siloxane units providing a weight average molecular weight for the binder in a range of about 0.5 KDa to about 10 KDa, preferably about 0.5 KDa to about 5 KDa, more preferably about 1 KDa to about 5 KDa, most preferably about 1 KDa to about 3 KDa., especially about 1 KDa to about 2 KDa.

Embodiments of the linker of the film forming composition may have the number of their monomeric units chosen to provide a weight average molecular weight for the linker in a range of about 5 KDa to about 50 KDa, preferably about 5 KDa to about 30 KDa, more preferably about 5 KDa to about 20 KDa, most preferably about 8 KDa to about 20 KDa, especially about 10 KDa to about 20 KDa. The weight average molecular weight of the linker will primarily be provided by the number of dimethylsiloxane units present in backbone of the polydimethylsiloxane-type silicone linker.

The binder and linker molar concentrations in the film forming composition deliver a ratio of Michael to aza groups. In some embodiments of the film forming composition, the binder provides a number of α,β unsaturated alkenoyloxy groups (Michael groups) equal to the number of organoamine groups (aza groups) of the linker. In preferred embodiments of the film forming composition, the binder provides an excess number of Michael groups relative to the number of aza groups of the linker. This ratio enables Michael-aza addition of the binder with the amine groups of the small molecule of the pretreatment composition. In more preferred embodiments of the film forming composition, the binder provides at least 2 to 8 Michael groups per 2 to 6 aza groups of the linker.

Pre-Treatment Composition

The significant remanence, wear-fastness and resistance to environmental attack of the color coating on keratin fibers according to aspects of the invention may be developed through interaction between and among any one or more of the components of the film forming composition, the pre-treatment composition and the keratin fibers, preferably anagenic hair. The interactions are complex and involve cooperation of binder and pretreatment small molecule components through covalent bonding, hydrogen bonding, dipolar interaction, molecular intertwining. The interactions also are believed to involve at least in part covalent bonding and non-covalent interactions between and among the keratin fiber surfaces and the components of the pre-treatment composition and the components of the film forming composition. Embodiments of the pre-treatment composition may comprise organosilicone and/or silicone small molecules that incorporate alkoxysilyl groups and preferably also amine groups.

The organosilicone and/or silicone small molecules of the pre-treatment composition preferably have a weight average molecular weight of from about 100 Da to about 1 KDa.

Embodiments of the pretreatment compositions as small molecules comprise silicon cores of from 1 to 6 silicon atoms, preferable 1 to 3 silicon atoms, more preferably 1 or 2 silicon atoms and most preferably one silicone atom. Alternatively, the small molecules comprise an organic core of 1 to 10 carbons, or a small number of repeat monomeric units. The silicone and organic core small molecule embodiments of the pre-treatment composition may also comprise one or more organoamine groups and one or more alkoxysilyl groups. The number of amine groups and alkoxy silyl groups present in the small molecule will depend upon the kinds of inter molecular connections desired for the pre-treatment composition. In particular, the small molecule may contain at least one and preferably two organoamine groups for covalent, polar, dipole, ionic and/or electrostatic interaction with components of the film forming composition and at least such polar groups as carboxyl and amide groups of the keratin protein at the surfaces of the keratin fibers. In particular, the small molecule will also contain at least two and preferably at least three alkoxysilyl groups. The alkoxysilyl groups may provide covalent silicon-oxygen-carbon bond formation with monomeric units of keratin protein which carry pendant hydroxyl groups, such as serine, threonine and tyrosine. The alkoxysilyl groups may also interact with keratin amino acid moieties carrying carboxyl side chains, such as aspartic acid and glutamic acid. In this instance, the intermediate carboxylsilyl group may further combine with amine groups from any source to form amide linkages. The alkoxysilyl groups may also interact with cysteine to form a thio analog silicon-sulfur-carbon bond formation or interact by dipolar and/or ionic interaction.

The small molecule embodiment of the pre-treatment composition may be conceptualized as Formula III:

[(H₂N)—((CH₂)_(m)—NH)_(o)—(R¹⁴)_(n))]_(a)—[RO_(t)Me_(3-t)Si—O]_(b)—(—SiMe₂-O)_(p)—(—SiMeOR—O)_(q)—[—SiMe_(2-r)[(CH₂)_(m′)—NH₂]_(r)—O]_(s)-[A]_(c)-[—SiMeMe_(2-v)-O]_(u)—SiMe_(3-t)OR_(t)   Formula III

Formula III incorporates several additional functional groups with the organosilyl small molecules having the alkoxysilyl functional group. Some of these are: a) organoamine groups, b) additional alkoxysilyl groups, mercapto groups, multialkylamino groups, α,β unsaturated alkenoyloxy groups such as (meth)acryloyl, ureido, dithio, alkyl, aromatic and similar groups as described by A.

To accomplish these variations, the R groups and designators have the following definitions. The R and R¹⁴ groups are alkyl groups. R provides the alkyl group of the alkoxysilyl group and may be methyl or ethyl. R¹⁴ is a C1-C6 alkylenyl group.

Group A may be a divalent group including dithio, diazo, urethanyl, ureido, or C1-C6 alkylenyl connecting left and right sections of the small molecule. Alternatively, group A may be a terminal group including C1-C14 alkyl, C1X-C14X heteroalkyl with X as N, S or O either in chain or as a terminus such that this group may be ω-aminoalkyl, ω-mercaptoalkyl, ω-hydroxyalkyl or the alkyl with N, S or O in the alkyl chain, C1-C6 alkoxy, C7-C14 arylalkyl, C6X-C14X heteroarylalkyl with X as N, S or O, C1-C6 alkylenyl(meth)acrylate or C1-C6 alkylureido.

Designators m and m′ may be an integer of 1 to 3. Designators o, n, b, r, s, c, u may be zero or 1. Designator a may be zero, 1 or 2. Designator v may be zero, 1 or 2 such that when a is 2, v is 2 and when a is 1, v is 1 and when a is zero, v is 1 or zero. Designator t may be 1 to 3. Designators p and q independently may be zero or an integer of 1 to 6. Designator t may be zero or an integer 1-3.

For Formula III, the designators a as zero and b as 1 describe the small molecule with alkoxysilyl groups at both termini. These same designators with a as 1 and b as zero describe a small molecule with an alkoxysilyl group at one terminus and an organoamine group at the other terminus. The designators m, o, n and m′ determine the size of the organoamine group and the number of secondary amines present. The designator p determines the number of dimethylsiloxane units in the small molecule. The designators q and s determine whether or not the small molecule has pendant alkoxysilyl groups (designator q) and/or has pendant organoamine groups (designator s).

The group A may or may not be present depending on whether c is 1 or zero. Group A may be a divalent group including dithio, diazo, urethanyl, ureido, or C1-C6 alkylenyl connecting left and right sections of the small molecule. Alternatively, group A may be a terminal group including C1-C14 alkyl, C1X-C14X heteroalkyl with X as N, S or O either in chain or as a terminus such that this group may be ω-aminoalkyl, ω-mercaptoalkyl, ω-hydroxyalkyl or the alkyl with N, S or O in the alkyl chain, alkoxy, C7-C14 arylalkyl, C6X-C14X heteroarylalkyl with X as N, S or O, C1-C6 alkylenyl(meth)acrylate or C1-C6 alkylureido when c is 1 and a, b, p, q and s are all zero. In this instance, u may be 1 and v is 1 so that the terminal A group is bound to a dimethylsiloxane chain terminated by an alkoxysiloxane group. Alternatively, u may be zero so that the A group is bound to the silicon of the alkoxysilyl terminus. Finally, with A as an alkylenyl, c as 1, b, p, q, s and v as zero and a as 2, the small molecule has two aminoalkyl groups bonded to A as alkylenyl which in turn may be bonded to a dimethylsiloxane unit (u as 1) or to an alkoxysilyl terminus (u as zero).

Exemplary embodiments of the small molecule component of the pre-treatment composition include but are not limited to APTES, triethoxysilylamine, 1,1,1-triethoxy, 2,2-dimethyl-2-aminodisiloxane, aminoalkylmonoethoxydimethylsilane, aminoalkyldiethoxymethylsilane and aminoalkyltriethoxysilane with 1 to 6 carbons in each alkyl group, preferably 2 or 3 carbons;

Another exemplary embodiment is (EtO)₃Si—O-(Me₂SiO)_(n)—SiMe₂(CH₂)_(m)NH₂ with n as 1 to 3 and m as 2 to 6, preferably 2 or 3.

Yet another exemplary embodiment is (EtO)₃Si—O-(Me₂SiO)_(n)—(SiOMe_(2-t)((CH₂)_(o)NH₂)_(q)—SiMe₂(CH₂)_(m)NH₂ with n as 1 to 3, t as 1 or 2, o as 1 to 6 preferably 2 or 3, q as zero, 1 or 2 and m as 2 to 6, preferably 2 or 3.

An additional exemplary embodiment is (EtO)₃Si—O-(Me₂SiO)_(n)—(SiOMe₂-((CH₂)_(o)NH₂)_(q)—(CH₂)_(r)—O—SiMe₂(CH₂)_(m)NH₂ with n as 1 to 3, t as 1 or 2, o as 1 to 6 preferably 2 or 3, q as zero, 1 or 2, r as 1-6, and m as 2 to 6, preferably 2 or 3. This embodiment provides A as an alkylenyl group.

When o, p, q, s, c and u are zero, a is 1, n is 1, R¹⁴ is propyl, R is ethyl and t is 3, the small molecule is aminopropyl triethoxy silane having the acronym APTES.

When m is 3, o and n are each 1; R¹⁴ is propyl; b, p, q, s and c are zero, R is ethyl and t is 3, the small molecule is N-(3-aminoprop-1-yl)-3-aminoprop-1-yl triethoxysiloxane.

When m and o are zero, n is 1, R¹⁴ is propyl, a is 2; b, p, q, s and u are all zero; c is 1, A is CH and t is 3, the small molecule is di(aminopropyl) methyl triethoxysilane. With this same configuration but with c as zero and u as 1, the small molecule is di(aminopropyl)methylsilyloxytriethoxysiloxane which is (H₂N(CH₂)₃)₂SiMeOSi(OET)₃.

Praeparatur and Fundamenta Techniques

A typical procedure for coloration of anagenic hair may involve application of a permanent oxidative dye formulation or may involve semi-permanent application of a direct dye or may involve temporary coloration that can be removed by a single mild shampoo washing. These three techniques for hair coloration traditionally are applied to anagenic hair without a prior wash of the anagenic hair. The presence of sebum, fatty acids (F layer), natural oils, sweat residue, mineral excretion from skin pores are traditionally regarded as helpful in the practice of these coloration techniques. Of course, if the anagenic hair also contains dirt particles, it is usually combed thoroughly to remove dirt debris but the natural oils, secreted minerals, sebum, fatty acids and the like remain.

It is expected therefore that the remanent results demonstrated by formation of a color coating according to the invention on a treated or untreated tress would also be demonstrated by formation on anagenic hair of a color coating according to the invention. In contrast to this expectation, and as shown by the mimic tress experiments described below, a color coating formulated onto anagenic hair such as hair on the scalp of a female hair model does not display long-lasting remanence. The hue, intensity and shade of the color coating on anagenic hair such as that of a model rapidly decreases with each shampooing and by 3 shampoo washes or less, the color coating is gone, especially for color coating on the root portion of anagenic hair.

In contemplation of these results, it was realized that treated and untreated tresses fundamentally differ in at least one respect from anagenic hair. The treated and untreated tresses which are the typical universal substrate for keratin fiber experimentation are not connected to hair follicles and do not receive continuous secretions of sebum, natural oils and fatty acid as well as sweat and mineral secretions from adjacent skin pores. This realization led to experimentation to improve remanence on anagenic hair by converting it to hair like that of treated and untreated tresses. These attempts involved initial removal of sebum, natural oils, fatty acid secretions, sweat and mineral secretions by detergent washing as is usually performed on cut hair being prepared for treated tresses. These attempts also failed. Subsequent body secretions appurtenant to the hair on the scalp of hair models were found to continue circumvention of the remanence result experienced with treated and untreated tresses.

Continued research has led to a combination of aspects that have enabled development of a color coating on anagenic hair that displays remanence similar to that displayed by treated and untreated tresses. These aspects include at least the techniques of Praeparatur and Fundamenta in combination with the Pretreatment Composition with small molecules described above.

Praeparatur Technique

Substantially complete initial removal of sebum coating the surfaces of anagenic hair delivers a primed hair strand surface exposing the microscopic topographic variability provided by keratin protein at this surface. To obtain such keratin fiber priming, a Praeparatur technique is applied. The Praeparatur technique may be any priming operation that removes sebum from the surfaces of keratin fibers. Exemplary Praeparatur techniques include use of one or more applications of a non-conditioning or substantially non-conditioning surfactant which is free of conditioning actives or substantially free of conditioning additives such as silicones, e.g., amodimethicone, or cetrimonium chloride and polymers such as the polyquaternium versions of cellulose and guar gum derivatives. This technique calls for one or more applications of the surfactant in an aqueous or aqueous-alcoholic medium with optional agents for ionicity and pH control in which the kinds and concentrations of components are adjusted to achieve the desired priming effect. The technique involves use of a mild to moderate aqueous composition of an anionic, non-ionic, amphoteric or zwitterionic surfactant at a concentration beginning at about 2 wt % and escalating to about 30 wt %, preferably up to about 25 wt %, more preferably up to about 10 wt % to about 25 wt % relative to the total weight of the composition. The surfactant composition may also include agents for adjustment of viscosity and ionicity and optional adjustment of pH from acidic to neutral to basic. The surfactant composition may begin with a mild surfactant such as a non-ionic or its mixture with other surfactants and may escalate to higher concentrations of anionic surfactant. A preferable surfactant is an anionic surfactant displaying amphiphilic properties such as an alkali metal salt of a C8-C16 alkyl carboxylate, phosphate, sulfonate, sulfate in which the strength of amphiphilic character increases from carboxylate to sulfate. The initial nonionic surfactant used may be followed by a stronger anionic surfactant and then by a solubilizing anionic surfactant having either a PEG group such as PEG-2 to PEG-20, preferably PEG-2 to PEG-5 for increased hydrophilicity or a PPG group such as PPG-2 to PPG-5 for increased lipophilicity inserted between the anionic head and the alkyl lipophilic tail of the anionic surfactant. Yet stronger solubilizing media may be formulated by increasing the ionic strength and adjusting the pH. Ionicity builders such as alkali metal sulfates, carbonates, phosphates, nitrates and/or xylene sulfonate may be added. The nature of the medium may also be adjusted to provide organic solvents that are capable of solubilizing oils and sebum. Included are C2 to C8 alcohols, preferably isopropanol, isobutanol and neohexanol. This escalating priming treatment is designed to escalate in mild stepwise fashion so as to avoid overchallenge of the hair.

This escalating priming treatment may be coupled with mechanical agitation such as by a fine tooth comb and/or by a sound vibration such as with a ultrasound device operating at least at 20K Hertz. The mechanical and/or sound vibration can agitate the anagenic hair strands to loosen coatings of sebum, natural oils and secreted sweat and minerals. The ultrasound device may be designed as a fine tooth comb, the teeth of which vibrate to produce the ultrasound. Alternatively, the ultrasound device may be a hand-held generator held in combination with a fine tooth comb which is run through the anagenic hair under the above described priming conditions.

Fundamenta Technique

The Praeparatur technique often will be sufficient to prime a fiber surface and allow adherence of the pretreatment small molecule with surface exposed protein. However, application of the Praeparatur technique to anagenic hair may not fully prime the bare surface protein of keratin fibers. In such instances, application of the Fundamenta technique may accomplish deep cleaning of the keratin fibers such as anagenic hair. The Fundamenta technique may be applied as a follow-on to use of the Praeparatur technique or applied without prior use of the Praeparatur technique or may be applied first with subsequent use of the Praeparatur technique. The Fundamenta technique structurally deep cleans the surface topography and chemical make-up of the surfaces of keratin fibers and removes the F layer coating on the keratin fibers. The technique also may but not necessarily adjust the topography of the fiber surfaces so as to enable better access of the pretreatment small molecules to the fiber surfaces. This technique may be accomplished by any deep cleaning operation that removes the F layer and deep cleans the keratin fiber surfaces. Exemplary activities include one or more of cold plasma discharge, surface oxidizer such as but not limited to ozone, peroxide and/or persulfate and/or a form of chlorite treatment and/or an alkali phase transfer tenside (PETT) such as a multi alkyl ammonium halide, examples of which are C2-C20 alkyl trimethyl ammonium chloride (CTAC) or bromide (CTAB) such as choline halide, cetyl trimethylammonium halide or stearyl trimethylammonium halide.

The cold plasma treatment may be accomplished by passing partially ionized gas over anagenic hair or mimic tresses. Cold plasma is a non-equilibrium atmospheric plasma of a gas such as air or oxygen and/or nitrogen having an effective gas temperature approximating ambient temperature, while the electron temperature may be much higher. The gas is passed between dielectric coated electrodes at a high AC voltage potential difference, or through an RF field. The electromagnetic field dislodges some electrons from the gas atoms to produce a cascade of ionization process which lead to the cold plasma stream. An example is an ozone generator which passes air through a high voltage spark discharge. Cold plasma generators are commercial devices designed for production of ambient temperature (cold) plasma. The plasma is transported through a flexible tube to a nozzle. The nozzle through which the plasma stream flows may be passed over the keratin fibers to accomplish plasma treatment. A typical treatment of a mimic hair tress involve passing the nozzle with flowing plasma over the keratin fibers for approximately 1 to 5 minutes, preferably about 1 to about 3 minutes.

The alkali phase transfer tenside treatment is accomplished by washing anagenic hair and/or mimic tresses with an aqueous solution of phase transfer tenside with an alkaline base or a nucleophile such as an alkoxide. A phase transfer tenside (PETT) generically is a C2-C20 multi-alkyl ammonium halide such as choline or preferably a C12-C20 alkyl trimethyl ammonium chloride or bromide, more preferably cetyl (C16) and/or stearyl (C18) trimethyl ammonium bromide (CTAB). The PETT may be formulated as a 0.1 wt % to 25 wt % aqueous solution. An alkali or thiol aqueous solution (basic alkali pH>10, basic thiol pH>7) of the PETT may be applied to a mimic tress or anagenic hair and massaged through the hair strands either by hand or by brush for a period of 5 to 30 minutes, preferably 5 to 15 minutes to obtain PETT treatment. Thereafter, the tress or anagenic hair, which is substantially saturated with aqueous, basic PETT, is repeatedly rinsed with shampoo in acidic medium to remove the PETT solution.

The surface oxidizer treatment is accomplished by exposing anagenic har or mimic tresses to a dilute oxidizer solution. The oxidizer solution may be formulated as an aqueous solution of a persulfate, hypochlorite, peroxide or ozone typically at a concentration of from about 0.5 wt % to about 10 wt %, preferably about 0.5 wt % to about 5 wt %, more preferably about 0.5 wt % to about 2 wt %. The oxidizer solution can be at an elevated pH, due to the presence of ammonia or MEA or sodium silicate or metasilicate. The oxidizer solution is applied to a mimic tress or anagenic hair and massaged through the hair strands either by hand or by brush for a period of from 10 seconds to about 5 minutes, preferably about 10 seconds to about 1 to 2 minutes. Thereafter the tress or anagenic hair, which is substantially saturated with oxidizer solution, is repeatedly rinsed with water to remove the oxidizer solution.

The basic and/or nucleophilic medium for use with any of the Fundamenta treatment may be any that does not swell the hair strands but will dissolve the resulting free 18-methyleicosanoic acid (F-layer acid). An example of such a medium is t-butoxide in t-butanol or an alkyl or aromatic thiol such as hexyl thiol or thiophenol in acetone.

It is believed that the Praeparatur and Fundamenta techniques enable intimate interaction of the pretreatment small molecule and the surfaces of anagenic hair strands. The Praeparatur and Fundamenta techniques prime and deep clean the hair strand surfaces to remove at least sebum and the F layer so that the small molecule is better able to adhere intimately with and within the peaks, shoulders, and valleys of the surfaces of the keratin fibers as well as with the microscopic topography involving the keratin protein in at the fiber surfaces. This ability of the small molecule is also related to its small size and reactive energy. As mentioned previously, the presence of the sebum and fatty acid F layer surrounding the surfaces of keratin fibers of anagenic hair presents a surprising problem with respect to treated and untreated tresses. The Praeparatur and Fundamenta techniques practiced in combination with the application of the pretreatment composition with small molecules enable this intimate adherence with the microscopic topography of the protein at the surfaces of the keratin fibers. Once in place, the small molecule embodiments are readily able to self-condense to form polysiloxane three dimensional networks in intimate adherence with these keratinaceous surfaces. Subsequent covalent interactions between remaining reactive groups of the condensed small molecule embodiments and the binder component of the film forming composition are believed to extend the three dimensional network. Because of the microscopic topographic adherence of the three dimensional network of condensed small molecules to the keratin surface proteins, it is believed that continued sebum and fatty acid secretions onto the keratin fiber shafts are unable to work their way (worm) underneath the network and dislodge it. The network, in turn is intimately interconnected with the three dimensional network formed through condensation of the binder of the film forming composition. The cooperation of these networks inter-adhered with the keratinaceous surfaces is believed at least in part to provide significant remanence of anagenic hair. These aspects according to the invention are believed to produce at least in part qualities and characteristics of the color coating on the keratinaceous surfaces and especially on the surfaces of hair strands of anagenic hair.

Medium

When applied to keratin fibers, the media of the film forming composition and pretreatment composition embodiments of the invention may be an organic compound that is capable of being intimately mixed or preferably will form a solution with a minor amount of water. The preferred media comprise embodiments of alcoholic solvents such as an alkyl alcohol of 1 to 6 carbons with no intentionally added water. Included are methanol, ethanol, propanol, isopropanol, ethylene glycol, propylene glycol, n-butanol, isobutanol, pentanol, neopentanol, isopentanol and n-hexanol. Preferred organic alcohols include ethanol, n-propanaol, isopropanol, n-butanol and isobutanol t-butanol and pentanol. More preferred organic alcohols include isopropanol and isobutanol. The alcoholic solvent may be intentionally combined with water in amounts up to about 10 weight percent, preferably up to about 5 weight percent, more preferably up to about 2 or 3 weight percent and most preferably up to about 1 weight percent relative to the total weight of the media. It is recognized that alcohol solvents absorb water from the atmosphere so that an alcoholic solvent with no intentionally added water may contain a slight amount of water. Although it is not a limitation of the invention, it is believed that the presence of water facilitates the condensation of the alkoxysilyl groups to silyloxysilyl groups by hydrolyzing the alkoxy groups to hydroxyl groups.

Additionally, the medium for the pretreatment composition may include a minor amount of acetic acid, such as from about 0.1 wt % to about 2 wt %, preferably from about 0.1 wt % to about 1 wt %, more preferably from about 0.1 wt % to about 0.5 wt % relative to the total weight of the medium. Alternatively, a 90%-95% aqueous medium with ethanol and acetic acid may be used for the pretreatment composition. The presence of acetic acid facilitates hydrolysis of the alkoxysilyl groups to hydroxysilyl groups and renders the small molecule of the pretreatment composition more soluble in water. When the minor amount of acetic acid is present in the aqueous-alcoholic pretreatment composition, the lifetime of the small molecule is on the order of a few hours. Consequently, this option for application of the pretreatment composition is typically conducted in small batches which are mixed and immediately used. The medium for the pretreatment composition may also include a balance among the amounts of alcohol, water and acetic acid present relative to the identity of the small molecule present. In some instances, the acid and/or water concentrations may be greater than in others. Determination of appropriate and/or optimum ratios of concentrations for the individual small molecule, the choice and amount of medium and the presence and amount of acid or alkali are within the ordinary experimental ability and technique of the laboratory technician.

The binder and linker of the film forming composition and the pretreatment composition are maintained separately until use. Packaging each in separate containers serves this purpose. Each of the binder, linker and small molecule of the pretreatment composition may be maintained in a medium that does not interact with the reactive groups. Suitable media for the binder and linker are non-aqueous organic solvents such as but not limited to the alcohols mentioned above, preferably isopropanol and isobutanol or liquid hydrocarbon or silicone solvents. The media for separately maintaining the binder, linker and small molecule should not include water or agents that would hydrolyze alkoxysilyl groups. Typically, the binder, linker and small molecule preparations for storage may be formulated as ready to use concentrations or may be concentrates which are to be diluted with appropriate media to prepare them for use or may be ready to use concentrations for application to keratin fibers.

When the film forming composition and the pretreatment composition are prepared for application to keratin fibers, they may be formulated with a single phase alcohol or alcohol medium as described above or may be formulated as a two phase aqueous medium with water or water-alcohol as the continuous phase and a water or water-alcohol immiscible organic liquid as the discontinuous phase. The continuous phase may carry water soluble constituents while the discontinuous phase may carry constituents such as those of the film forming composition and the alkoxysilyl small molecule of the pretreatment composition that would react with water. The discontinuous, non-aqueous phase will tend to isolate such compounds from degradation by water. Preferably, in situations when water is to be part of a medium but one or more of the components of the film forming composition and pretreatment composition are sensitive to water, the film forming composition and pretreatment composition may be maintained in a non-aqueous environment until they are ready for dressing on keratin fibers. At the application stage, a single phase or two phase medium may be prepared as appropriate.

The polarity and protonic character of the medium are important for control of the several reactions that occur when the components of the film forming composition and pretreatment composition are combined. These reactions include the reactive termini/pendant alkoxysilyl groups which undergo alkoxysilyl condensation to form silyloxysilyl linkages as well as the aza-Michael addition. Preferably, the medium for application of the film forming composition and the pre-treatment composition is polar and can support the condensation and addition reactions. For both of the film forming composition and pretreatment composition, isopropanol or isobutanol as described above is appropriate. The application media may be combined with the separately stored concentrates of binder, linker and small molecule and the media of the stored concentrates preferably will be at least partially to substantially miscible with the application media.

The medium may be independently present in each of the film forming composition and the pretreatment composition in an amount ranging from about 0.1% to about 99% by weight, such as from about 1% to about 98% by weight, for example ranging from 50% to 95% by weight relative to the total weight of which of the film forming composition and pretreatment composition is under consideration.

Viscosity, Compositional Constituent Concentrations

The viscosities of the film forming composition and pretreatment composition function to hold them in place on the keratin fibers while the color coating is formed. The viscosity substantially avoids free translational flow of these compositions. Free translation flow would cause the compositions to rapidly run and drip off the surfaces of the hair strands. Nevertheless, the viscosity is not so high that it will not undergo self-leveling to coat the keratin fibers substantially uniformly. Appropriate viscosity of the compositions is the result of the interaction of the various constituents of the film forming and pretreatment compositions, their concentrations, the pigment microparticles, and as appropriate, an optional viscosity control agent, an optional suspending agent and an optional thickening agent.

Generally, the viscosity of the film forming and pretreatment compositions may range from about 0.001 to about 2000 Pa s⁻¹. Viscosity measurements are carried out on a controlled stress rheometer e.g. Using an AR2000 type manufactured by TA Instruments, or equivalent instrument. A 6 cm flat acrylic cross hatched parallel plate geometry (TA item 518600.901) and a stainless steel cross hatched base plate (TA item 570011.001) are used. The rheometer is prepared for flow measurements as per standard manufacturer procedure. The parallel plate geometry gap is set to 1000 microns. The flow procedure is programmed to the rheometer with the following conditions: continuous stress ramp 0.1-300 Pa over 2 minutes at 25° C., including 250 measurement points in linear mode. The product is loaded into the geometry as per standard procedure and the measurement commences at 5 min after the mixture preparation. Shear stress value at 10 sec⁻¹ shear rate is obtained from the shear stress vs. shear rate curve, and the corresponding viscosity is calculated by dividing the obtained shear stress by 10.

The concentration of the binder and linker constituents in the film forming composition and the concentration of the small molecule constituent in the pretreatment composition may each independently range from about 0.1% to about 90%, preferably about 1% to about 40%, more preferably about 2% to about 30%, most preferably about 2% to about 15% by weight relative to the total weight of the composition. As discussed above, the viscosity is managed so that the film forming and pretreatment compositions will not run off the surfaces of strands of hair yet will level and flow to substantially coat those surfaces. Development of appropriate viscosity in part by management of the concentrations of the constituents of the film forming and pretreatment compositions can be experimentally determined by routine methods such as formulation of several samples of differing concentrations of constituents in these compositions, coating those samples on a hair tress and observing the flow, spread and leveling of the composition on the hair strands.

The film forming and pretreatment compositions can be applied simultaneously, sequentially or in pre-combined form to keratin fibers such as a hair tress using the coloring procedure described herein afterwards. The top of the hair strand, where it is glued together is fixed such that the hair is aligned vertically downwards. After a 5 minute dwell time it is observed if any and how much product has dripped from the hair tress. The results obtained from the several samples can be plotted against flow time and leveling time to determine an appropriate concentration or range of concentrations of the constituents of the film forming and pretreatment compositions.

The extent of linking between and among the reactive constituents of the film forming and pretreatment compositions may be controlled by manipulation of ratios, amounts present and concentrations as well as by physical means as described above so that the mechanical and chemical properties of the color coating as described herein are preserved. These properties include ability to adhere to hair strands, ability to maintain flexibility and free flowing character of the hair, ability to provide remanence, avoidance of stickiness and avoidance of clumping.

The glass transition temperatures of the crosslinked binder and linker of the film forming composition and the polymerized small molecule of the pretreatment composition in part contribute to the flexibility, strength, hardness and similar qualities of the color coating on the keratin fiber surfaces. The glass transition temperatures of these embodiments preferably are well below ordinary minimum environmental temperatures such as −100° C. to −30° C. The glass transition temperature or T_(g) determines the solid-solid transition of the polymer from a hard glassy material to a soft rubbery material. For the purposes of the color coating on keratin fibers, the soft, rubbery, elastic state is the state to be achieved. If the T_(g) of the color coating is too high, such as above ambient temperature the color coating on the keratin fibers will be stiff and inflexible. This is an undesirable result. The coating should be soft, flexible, elastic and unnoticeable to touch and sight yet should not flake, break-up or otherwise release from the keratin fiber, and especially from anagenic hair, when stroked by a hand or brushed with a brush. The Tg of a color coating can be measured using ASTM D7426-08 (2008).

Plasticizer

If the glass transition temperatures of the color coating and/or the constituents of the film forming and pretreatment compositions are too high for the desired use yet the other properties thereof are appropriate, such as but not limited to color and remanence, one or more plasticizers can be combined with the constituents of the film forming and pretreatment composition embodiments so as to lower the T_(g) of the constituents and provide the appropriate feel and visual properties to the color coating. The plasticizer can be incorporated directly into one or both of the film forming and pretreatment compositions or can be applied to the hair following formation on the keratin fibers of the color composition of the combined film forming and pretreatment compositions but substantially curing the color composition to form the color coating on the keratin fibers. The plasticizer can be chosen from the plasticizers typically used in the field of application. Appropriate selection includes choice of a plasticizer that does not interfere with or compete with the aza-Michael addition and the alkoxysilyl condensation.

The plasticizer or plasticizers can have a molecular mass of less than or equal to 5,000 g/mol, such as less than or equal to 2,000 g/mol, for example less than or equal to 1,000 g/mol, such as less than or equal to 900 g/mol. In at least one embodiment, the plasticizer, for example, has a molecular mass of greater than or equal to 40 g/mol.

Thus, the film forming and pretreatment compositions can also comprise at least one plasticizer. For example, non-limiting mention can be made, alone or as a mixture, of common plasticizers such as: glycols and derivatives thereof, silicones, silicone polyethers, polyesterpolyols; adipic acid esters (such as diisodecyladipate), trimellitic acid esters, sebacic acid esters, azalaeic acid esters; nonlimiting examples of glycol derivatives are diethylene glycol ethyl ether, diethylene glycol methyl ether, diethylene glycol butyl ether or diethylene glycol hexyl ether, ethylene glycol ethyl ether, ethylene glycol butyl ether, or ethylene glycol hexyl ether; polyethylene glycols, polypropylene glycols, polyethylene glycol-polypropylene glycol copolymers, and mixtures thereof, such as high molecular weight polypropylene glycols, for example having a molecular mass ranging from 500 to 15,000, for instance glycol esters; propylene glycol derivatives such as propylene glycol phenyl ether, propylene glycol diacetate, dipropylene glycol ethyl ether, tripropylene glycol methyl ether, diethylene glycol methyl ether, and dipropylene glycol butyl ether. Such compounds are sold by Dow Chemical under the names DOWANOL PPH and DOWANOL DPnB; acid esters, for example esters of carboxylic acids, such as triacids, citrates, phthalates, adipates, carbonates, tartrates, phosphates, and sebacates; esters derived from the reaction of a monocarboxylic acid of formula R₁₁COOH with a diol of formula HOR₁₂OH in which R₁₁ and R₁₂, which can be identical or different, are chosen from a linear, branched or cyclic, saturated, or unsaturated hydrocarbon-based chain containing, for example, from 3 to 15 carbon atoms for example the monoesters resulting from the reaction of isobutyric acid and octanediol such as 2,2,4-trimethyl-1,3-pentanediol, such as the product sold under the reference TEXANOL ESTER ALCOHOL by the company Eastman Chemical; oxyethylenated derivatives, such as oxyethylenated oils, such as plant oils, such as castor oil; mixtures thereof.

Among the esters of tricarboxylic acids mention can be made of the esters of triacids wherein the triacid corresponds to formula

wherein R is a group —H, —OH or —OCOR′ wherein R′ is an alkyl group containing from 1 to 6 carbon atoms. For example, R can be a group —OCOCH₃. The esterifying alcohol for such tricarboxylic acids may be those described above for the monocarboxylic acid esters.

The plasticizer can be present in either or both of the film forming and pretreatment compositions in an amount from about 0.01% to 20%.

Pigment

The film forming and pretreatment composition embodiments of the present invention make it possible to obtain colored coatings, without substantially altering the keratin fibers. As used herein, the terms “pigment(s) and color body(ies)” are synonyms and generally refer to any particle colorant or amorphous insoluble color material/body having or containing pigment material that gives keratin fibers color including black and white, such as titanium dioxide that gives only white color to keratin fibers. The pigments are substantially water-insoluble. The pigments, to distinguish from dyes presented in molecular from, are also referred to as pigment microparticles or pigment particles. The terms pigment microparticles and pigment particles are synonymous and are used herein interchangeably. The pigments can be organic, inorganic, or a combination of both. The pigments may be in pure form or coated, for example with a polymer or a dispersant.

Selections, multiple kinds and varying forms of the pigment microparticles as described in the following passages can be incorporated in any of the first, second and third components of the multicomponent composition, or can be incorporated in any two of these components or in all three. Preferably, pigment microparticles can be incorporated in either or both of the first and second components. More preferably, pigment particles can be incorporated in the first component.

The at least one pigment that can be used can be chosen from the organic and/or mineral pigments known in the art, such as those described in Kirk-Othmer's Encyclopedia of Chemical Technology and in Ullmann's Encyclopedia of Industrial Chemistry. The pigments comprised in the microparticles comprising at least one pigment will not substantially diffuse or dissolve into keratin fibers. Instead, the pigment comprised in the microparticles comprising at least one pigment will substantially remain separate from but attached to the keratin fibers.

The at least one pigment can be in the form of powder or of pigmentary paste. It can be coated or uncoated. The at least one pigment can be chosen, for example, from mineral pigments, organic pigments, elemental metal and their oxides, and other metal modifications, lakes, pigments with special effects such as nacres or glitter flakes, and mixtures thereof.

Pigment Shape

The pigment microparticles can have any suitable shape, including substantially spherical. But the pigment microparticles can also be oval, elliptical, tubular, irregular, etc., or even combinations of various shapes. In addition, the pigment microparticles can have two dimensions, length and width/diameter, of similar magnitude. In addition, the pigment microparticles can be micro platelets, i.e. having a thickness that is substantially smaller than the planar dimension. For example, five, ten or even 20 times smaller in thickness than in the planer dimension. In one embodiment with any of the reactive components of the instant invention, the pigments may be surface treated, surface coated or encapsulated.

Pigment Size

The pigments can be present in the composition in undissolved form. Depending on the shape, the pigments can have a D50[vol] particle diameter of from 0.001 micron to 1 micron.

According to an embodiment, the particle size distribution, either relative to the number or volume of the particles, of the pigment microparticles can be at least bi-modal. A bi-modal particle size distribution has two distinct peaks which are spaced relative from, while tri-modal particle size distribution has three distinct peaks. The term “peak” means a local maximum of the distribution curve. The “distance” between two peaks, expressed relative to the particle size, can be at least 0.05 micron, preferably at least 0.1 micron, such as at least 0.2 micron. Providing an at least bi-modal particle size distribution allows to tailor the optical appearance of the colored hair. For example, the scattering properties varies with the particle size so that particles of different size scatter the light into different directions.

Pigments made from metal and metal like materials which can conduct electricity, and which can absorb light and re-emit the light out of the metal to give the appearance of strong reflectance. While not wishing to be bound by any specific theory, it is believed that the absorbed light will induce alternating electric currents on the metal surface, and that this currents immediately re-emit light out of the metal. Such pigment microparticles can be platelets, e.g., having a thickness that is substantially smaller than the planar dimension. For example, about five, about 10 or even about 400 times smaller in thickness than in the planer. Such platelets can have a planar dimension less than about 30 nm, but with a thickness less than about 10 micron wide. This includes a ratio of 10000 to 30, or 333. Platelets larger in size, such as 50 microns are even available in this thickness of 10 microns, and so the ratios can even go up to 2000.

The pigment microparticles can be a composite formed by two different types of pigment microparticles. Examples include a composite of a 2-dimensional microparticle and at least one micro spherical particle (microsphere), a composite of different micro spherical particles, and a composite of different 2-dimensional particles. Composite particles formed by 2-dimensional microparticles to which micro spherical particles adhere provide an attractive alternative to a pure mixture of 2-dimensional microparticles and micro spherical particles. For example, a metallic 2-dimensional microparticle can carry one or more micro spherical particle such as one or more organic micro spherical particle. The micro spherical particles attached or bonded to the 2-dimensional microparticle can be formed of the same pigment material or can be formed of different pigment material. Composite microparticles formed of 2-dimensional microparticles and micro spherical particles can provide multiple functionality in one particle such as (metallic) reflectance and dielectric scattering, reflectance and absorption.

The pigment microparticles can be both light scattering and absorbing for wavelengths of visible light. While not wishing to bound by any specific theory, it is believed that such pigments can provide both some visual effect of lightening the hair. Such pigment microparticles can have a D50[num] value between about 50 nm and about 750 nm, between about 100 nm and about 500 nm or between about 150 nm and about 400 nm. Such materials have a refractive index above about 1.5, above about 1.7 or above about 2.0.

According to an embodiment, different pigment microparticles are combined to provide reflective, transmitting and refractive properties of the hair colored with the color composition described herein. A microparticle combination can be a material composite using at least two different pigment materials to form the pigment microparticles. In addition to, or alternating to, the microparticle combination, a mixture of separate pigment microparticles of different type can be used to bring about the desired reflective, transmitting and refractive properties.

The composite pigments, combination of pigments, and mixtures of pigment microparticles eliminate, or at least significantly reduce, hair penetration and scattering by light and thus eliminate the perception of pigment of natural hair color change.

Pigment Concentration

The film forming composition for coloring hair fibers according to the present disclosure comprises microparticles comprising at least one pigment. The film forming composition comprises from about 0.01% to about 40%, about 0.05% to about 35%, about 0.1 to about 25%, or about 0.15% and about 20% pigment(s), by weight of the film forming composition.

Color Gamut for Pigment Blends

CIE L*a*b* (CIELAB) is a color space specified by the International Commission on Illumination. It describes all the colors visible to the human eye and serves as a device-independent model to be used as a reference.

The three coordinates of CIELAB represent the lightness of the color (L*=0) yields black and L*=100 indicates diffuse white; specular white may be higher), its position between red/magenta and green (a*, negative values indicate green while positive values indicate magenta) and its position between yellow and blue (b*, negative values indicate blue and positive values indicate yellow).

Since the L*a*b* model is a three-dimensional model, it can be represented properly only in a three-dimensional space. Two-dimensional depictions include chromaticity diagrams: sections of the color solid with a fixed lightness.

Because the red-green and yellow-blue opponent channels are computed as differences of lightness transformations of (putative) cone responses, CIELAB is a chromatic value color space.

In the present invention, the color gamut is determined by preparing samples of the film forming composition without pigment and the adding each pigment to be tested to individual samples of the film forming composition. Samples with pigment are prepared and applied to tress substrates. The samples are cured and then tested for coloration so that the resulting CIELAB lightness or L* value of the colored hair is 60±2. The level of pigment needed will depend on the pigment being tested. For example, hair tresses (Kerling, Natural White special quality) can be prepared as described using samples of a film forming composition applied alone as described in the present invention. A Minolta spectrophotometer CM-2600d can be used to measure the color of the cured and dried hair tresses, five points on both the front and back sides, and the values averaged. The D65 L*a*b values can be calculated. When at least three pigments have each been measured such that their resulting colors reside within the target L* values of 60±2 the color gamut can be calculated. First the lengths of each side of the resulting triangle of each combination of three pigments in the a*b plane are computed using the following expressions. To calculate the distance between pigments 1 and pigment 2 the following equation is used:

Side Length SL₁₂=((a _(pigment 1) −a _(pigment 2))²+(b _(pigment 1) −b _(pigment 2))²)^(0.5).

This is computed for each pair of pigments. Then for a series of three pigments.

The resulting color gamut is calculated using the expression:

Color Gamut=(S(S−SL₁₂)(S−SL₁₃)(S−SL₂₃))^(0.5)

wherein SL₁₂, SL₁₃, and SL₂₃ are the three lengths of the sides of the triangle within the a*b plane, and S=(SL₁₂+SL₁₃+SL₂₃)/2. Where more than three pigments are used, this calculation can be performed for each combination of the three pigment from the more than three pigments used, and the largest Color Gamut is selected.

The color coating embodiments of the present invention can also have a color gamut of greater than 250, greater than 500, greater than 750, greater than 800, greater than 900, greater than 1100 or even greater than 1250.

Experiments Performed for Color Gamut

Using the above expression, for each combination of three pigments possible from Color Gamut Tables 1, as illustrated below, the color gamut at a nominal L value of 60 was calculated.

These were formulated within an example formulation described later using an appropriate level of first, second and third compositions.

A few examples are exemplified of combinations of pigments and their resulting color gamut. One skilled in the art would be able to perform this for all of the possible permutations of pigments that are assessed according the description above.

FIGS. 1 to 6 show plots of color gamut triangles created for a series of three pigment selections. FIG. 1 shows that a combination of Pigment Green 36, Pigment Yellow 83 and Pigment Red 122 a large triangle is plotted in the a*b* color plane with an area of 1520. FIG. 2 shows that the combination of Pigment Green 36, Pigment Yellow 83 and Pigment Blue 60 gives a smaller triangle win an area of 925. FIG. 3 shows the combination of Pigment Black 7, Pigment Yellow 83 and Pigment Red 122 gives a smaller triangle win an area of 655. FIG. 4 shows the combination of Pigment Black 7, Pigment Blue 60 and Pigment Red 122 gives a smaller triangle win an area of 92.

A second series of example are made for how to assess more than three pigments and their resulting color gamut. When plotted a series of triangles can be plotted as shown and for each the areas is assessed. For such a composition the color gamut is defined as the largest of the triangles formed.

FIG. 5 shows a combination of Pigment Green 36, Pigment Yellow 83, Pigment Blue 60 and Pigment Red 122 a series of triangles are plotted with areas of 803, 925, 209 and 1520. The color gamut of this pigment composition is 1520. [Alternative calculation of total area would yield, 1728]. FIG. 6 shows a combination of Pigment Black 7, Pigment Yellow 83, Pigment Blue 60 and Pigment Red 122 a series of triangles are plotted with areas of 803, 57, 92 and 655. The color gamut of the pigment composition is 803 [alternative approach would be the same].

In an embodiment, a color composition (e.g., a set of a film forming composition and a pretreatment composition applied sequentially, simultaneously or in premixture to keratin fibers) can be applied to the hair in a sequential manner. For example it may be that this first set is applied to the hair which contains pigment microparticles that substantially scatter and/or reflect light such that it produces the visual effect of making the hair look lighter in color, after which a second set can be applied which contains pigment microparticles that substantially absorbs light and provides color to the hair and wherein the combination of the sequential addition of the first and second sets of color compositions provides the final hair color. For example, a first color composition may comprise metallic flakes and the second color composition may contain organic pigment microparticles. It may also be that more than a first and a second color composition are applied to the hair to achieve the desired color result, that three or more color compositions are applied.

The pH

The film forming and pretreatment composition embodiments in accordance with the present invention may have a pH adjustment attendant with their application to keratin fibers so that the pH upon application may range from about 4 to about 10, preferably about 5 to about 9 in systems which have a significant aqueous phase. The pH is preferably dynamically managed to control the rate of reaction of the reactive constituents of the film forming and pretreatment compositions. Maintaining a neutral pH during the mixing and preapplication stages involving these compositions controls the alkoxysilyl condensation under certain circumstances. The condensation may be initiated by reversion to as slightly acidic pH to an appropriate state for reaction. However, the aza-Michael addition may be appropriately managed by a slightly basic pH. An appropriate practice comprises adjustment of the pH during application of the film forming and pretreatment compositions so as to manage both in situ combinations.

Dispersants

It will be apparent to one skilled in the art that careful and selective choice of dispersant can help to maximize performance in terms of maximizing the amount of color produced from an immobilized film, maximizing the remanence or wash fastness, and enabling removal of the color.

The electrostatic, ionic and functional character of the dispersant is chosen to be compatible with and to not interfere with the reactive constituents of the film forming and pretreatment compositions. More preferably, the dispersant is chosen to be compatible with and miscible with the other components of the composition or compositions with and without medium.

The principle of choosing chemically similar dispersant with the binder polymer of the film forming composition can be followed to ensure maximum compatibility.

As well as compatibility as noted above, the other criterion in selecting dispersant(s) is their ability to enable pigment to be dispersed down to the primary particle size, preferably with the minimum amount of input mechanical energy. It will be recognized by someone skilled in the art that the concentration of dispersing agent is also a factor. In general, it is usually required that there is a minimum amount for dispersing activity and that below this, the composition is either not fully dispersed or the dispersant acts as a flocculant.

These two considerations together are used to define preferred materials and their respective concentrations.

It may also be the case, depending on the type of binder polymer used, that the binder itself is also a dispersant. In such cases it is possible that no further dispersing additive may be needed.

Combination of the dispersed pigment mixture with the film forming composition can be made in any manner. This order of combination of the dispersed pigment mixture with the film forming composition delivers the dispersed pigment mixture with the film forming composition layer and on top of the pretreatment layer. While the layers intermix to a slight to moderate to essentially full extent, at least a portion of the dispersed pigment mixture resides over the pretreatment layer. This arrangement of the coating at least in part enables removal of the coating when the “off” techniques described below are practiced.

Dispersants, Kinds, Properties and Chemistry

Dispersants are amphiphilic or amphiphathic meaning that they are chemical compounds possessing both hydrophilic (water-loving, polar) and lipophilic (fat-loving) properties. Dispersants are surface-active polymers that allow the homogeneous distribution and stabilization of solids, e.g. pigments in a liquid medium, by lowering the interfacial tension between the two components. As a result, agglomerates are broken up into primary particles and protected by a protecting dispersant envelope of a re-agglomeration.

The dispersants can be subdivided on the basis of the stabilization mechanism in

1. dispersants for electrostatic stabilization

a. Anionic dispersing additives

-   -   i. Polyacrylates     -   ii. Polyphosphates

b. Neutral dispersing additives, e.g, nonionic surfactants

c. Cationic dispersing additives, e.g., quaternary ammonium organic and/or silicone polymers

2. Dispersants for steric stabilization

Electrostatic Stabilization

The pigment surface is occupied by an additive carrying an ionic charge. All pigment particles are charged the same. The mutual repulsion by the charge is greater than the attractions of the pigment particles. The electrostatic stabilization has its relevance mostly in water-based paint compositions.

Polyanionic dispersing additives: polycarboxylates (mostly salts of polyacrylic acids), polyphosphates divided into linear polyphosphates and cyclic metaphosphates, polyacrylates

salts of polyacrylic acid, as cations, sodium and ammonium are preferred, these polyacrylates are water-soluble, technical products have molecular weights in the range of 2000 to 20,000 g/mol, optimum is about 8000 g/mol

Sodium and ammonium salts of the homo- or copolymers of acrylic acid, methacrylic acid or maleic acid

Steric Stabilization

The attractive forces between the pigment particles are effective only over relatively small distances of the particles from each other. The approach of two particles to each other can be prevented by molecules that are firmly anchored to the pigment surface and carry groups that extend from the surface and may reduce the potential for the pigments to contact one another. By sufficiently long chain lengths, agglomeration can be prevented. Also, the substances added to avoid agglomeration and other undesirable pigment particle interactions preferably are chosen to minimize or avoid interaction with the reactive polymers of the color composition.

Incorporation of Pigment in Disperant

The pigments described herein can be chosen and/or modified to be similar enough such that a single dispersant can be used. In other instances, where the pigments are different, but compatible, two or more different dispersants can be used. Because of the extreme small size of the pigment microparticles and their affinity, combination of the pigment microparticles and dispersant to form a substantially homogeneous dispersion that can subsequently be modified and/or diluted as desired is to be accomplished before combination with any or all of the first, second and third components of the multicomponent composition and preferably with only the first and/or second components.

The pigment microparticles can be dispersed and stabilized in the medium by one or more dispersants the properties and kinds of which are described above. The dispersant can either be added to the medium, or to a precursor medium or can form a coating on the microparticles to facilitate dispersion. It is also possible to provide the microparticles with a coating of a dispersant material and additionally provide a further dispersant to the medium, or to a precursor medium, which is used to form the final medium.

The dispersant, either added to the medium or provided as coating, facilitates wetting of the microparticles, dispersing of the microparticles in the medium, and stabilizing of the microparticles in the medium.

The wetting includes replacing of materials, such as air, adsorbed on the surface of the pigment microparticles and inside of agglomerates of the microparticles by the medium. Typically, a complete wetting of the individual microparticles is desired to singularize the particles and to break off agglomerates formed by microparticles adhering to each other.

After wetting, the microparticles can be subjected to de-aggregate and de-agglomerate step, generally referred to as dispersing step. The dispersing step typically includes the impact of mechanical forces such as shear to singularize the microparticles. In addition to shearing to singularize, the microparticles can be broken into even smaller microparticles using, for example, roller mills, high speed mixers, and bead mills. Usual practice involves substantially homogeneous dispersion of the pigments in dispersant through the use of high shear mixing; for example, through use to the appropriate ball mill, ultra high-pressure homogenizer or other composition known by those skilled in the art of pigment dispersion.

During wetting and dispersing, the exposed total surface area of the microparticles increases which is wetted by the dispersant. The amount of the dispersant may be gradually increased during dispersing to account for the increased surface area.

The dispersant also functions as de-flocculation agent keeping the dispersed microparticles in a dispersed state and prevent that they flocculate to form loose aggregates. This stabilization is also needed for long term storage purposes. Different type of stabilization such as electrostatic stabilization and steric stabilization are possible, and the type of dispersant is selected in view of the medium and the material of the microparticles.

The dispersant may be added to a dry powder of the pigment particles when the particles are milled to a desired size. During milling, or any other suitable technique to singularize the pigment particles or to break them into smaller part, the dispersant comes in contact with and adheres to the surface of the microparticles. Freshly generated microparticle surface during milling will be coated by the dispersant so that, after milling, the microparticles with a coating formed by the dispersant are provided.

The coating with the dispersant can also be carried out in a liquid carrier medium to which the dispersant is added. The microparticles can also be milled in the liquid carrier.

Optionally, the pigment microparticles may be coated with small molecules from a pretreatment composition. A portion of the pretreatment composition may be combined with the pre-milled pigment particles according to the procedures described above for wetting and dispersing the microparticles with dispersant. Following the wetting and dispersing procedures, the processed microparticles may be separated from excess pretreatment composition to produce microparticles coated with small molecules. It is believed that during this procedure, the coating of small molecules will begin to condense so that the coating will be at least a partially condensed net of silicone coating the individual microparticles. The coated microparticles may then be wetted and dispersed in dispersant as described above for the wetting and dispersing procedures.

Additive Components

Additive components for the film forming composition include suspending agents, leveling agents and viscosity control agents. The suspending agents help maintain the pigment particles in dispersed condition and minimize or negate their agglomeration. Suspending agents include fatty acid esters of polyols such as polyethylene glycol and polypropylene glycol. These are similar to plasticizers and function in similar fashion to allow pigment particles to “slip” by each other without retarding or binding interaction. They act as grease in this fashion. Additionally, suspending agents in part participate in promoting the stable dispersion of the pigment particles and avoid settling. The binder and linker of the film forming composition also participate through their solubilization or interaction with the pigment particles and with the medium. The suspending agents provide another factor for maintaining the stable dispersion. They not only provide the “grease” to facilitate Brownian movement but also in part stabilize through interaction as emulsifiers of the pigment particles in the medium. Optional components also are to be chosen so that they do not interfere or only minimally interfere with the reactive polymer coupling reaction.

Embodiments of the film forming composition in accordance with the present invention can also optionally contain at least one adjuvant, chosen, for example, from reducing agents, fatty substances, softeners, antifoams, moisturizers, UV-screening agents, mineral colloids, peptizers, solubilizers, fragrances, anionic, cationic, nonionic, or amphoteric surfactants, proteins, vitamins, propellants, oxyethylenated or non-oxyethylenated waxes, paraffins, C₁₀-C₃₀ fatty acids such as stearic acid or lauric acid, and C₁₀-C₃₀ fatty amides such as lauric diethanolamide.

Embodiments of the film forming composition in accordance with the present invention can further optionally contain one or more additives, including, but not limited to, antioxidants (e.g., phenolics, secondary amines, phosphites, thioesters, and combinations thereof), non-reactive diluents (e.g., ethylene glycol, di(ethylene glycol), tetra(ethylene glycol), glycerol, 1,5-pentanediol, ethylene glycol monomethyl ether, ethylene glycol dimethyl ether, triethylene glycol monomethyl ether, 2-ethoxyethanol, solketal, benzonitrile, hexamethylphosphoramide, 2-N-methylpyrrolidinone and N,N-dimethylformamide); dyes, fillers (e.g., silica; carbon black; clay; titanium dioxide; silicates of aluminum, magnesium, calcium, sodium, potassium and mixtures thereof; carbonates of calcium, magnesium and mixtures thereof; oxides of silicon, calcium, zinc, iron, titanium, and aluminum; sulfates of calcium, barium, and lead; alumina trihydrate; magnesium hydroxide and mixtures thereof), plasticizers (e.g., petroleum oils such as ASTM D2226 aromatic oils; paraffinic and naphthenic oils; polyalkylbenzene oils; organic acid monoesters such as alkyl and alkoxyalkyl oleates and stearates; organic acid diesters such as dialkyl, dialkoxyalkyl, and alkyl aryl phthalates, terephthalates, sebacates, adipates, and glutarates; glycol diesters such as tri-, tetra-, and polyethylene glycol dialkanoates; trialkyl trimellitates; trialkyl, trialkoxyalkyl, alkyl diaryl, and triaryl phosphates; chlorinated paraffin oils; coumarone-indene resins; pine tars; vegetable oils such as castor, tall, rapeseed, and soybean oils and esters and epoxidized derivatives thereof; esters of dibasic acids (or their anhydrides) with monohydric alcohols such as o-phthalates, adipates and benzoates; and the like and combinations thereof), processing aids, ultraviolet stabilizers (e.g., a hindered amine, an o-hydroxy-phenylbenzotriazole, a 2-hydroxy-4-alkoxybenzophenone, a salicylate, a cyanoacrylate, a nickel chelate, a benzylidene malonate, oxalanilide, and combinations thereof), and combinations thereof.

An additional additive may be a tactile hair modification agent. These may include, but are not limited to, a softening and/or lubricating and/or anti-static and/or hair alignment and/or anti-frizz benefit and/or impact on the keratin fibers.

Additional additives include filler materials such as but not limited to no chromatic material with a particle size of from about 2 nm to about 500 nm; macromolecular strands or nanoparticles composed of polyolefin such as polyethylene, polypropylene, polybutene, and combinations thereof, clays and mineralite substances such as but not limited to smectites, kaolins, illites, chlorites, attapulgites and intercalated aluminosilicate materials and purified formed thereof and combinations thereof. Additional mineral microparticles may be composed of inorganic metal oxides selected from the group consisting of silica, titanium oxide, zirconium oxide, aluminum oxide, magnesium oxide, boehmite alumina, hydrotalcite. Still other filler material includes but is not limited to carbon nanotubes micrographitic material such as nanofiller of graphite oxide mixed polymer, microbucky balls, clathrates, and crown composites of organic and mineral complexes. Additionally, the filler may be combined, complexed, contain or incorporate a polymer containing one of the members of a complementary reactive pair relating to the first and second components of the reactive polymer composition.

Additives may also include but are not limited to UV filter and UV block substances such as but not limited to avobenzone, bemotrizinol octocrylene, benzophenone-4, ethylhexyl methoxycinnamate, PABA, padimate O, PBSA, cinoxate, dioxybenzone, homosalate, menthyl anthranilate, octyl salicylate, parsol Max, tinosorb S and A2B, Uvinul, amioxate, polyvinylidene fluoride and other similar conjugated organic compounds, radical scavengers, triplet formation inhibitors, metal compounds incorporating chromium, titanium, zinc, nickel, manganese, iron, niobium, silver, gold, aluminum, hafnium, tantalum such as the oxides and similar forms thereof wherein the metal compounds absorb or reflect UV light.

Topcoat

The topcoat composition is a post dressing composition that may be applied at a later time by the person whose hair has been dressed with the color coatings (hereinafter the user). The topcoat composition may also be applied to the user's hair by a salon professional who has previously dressed the user's hair with color coatings or who is in the process of dressing the user's hair. The topcoat typically contains a readily evaporable medium such as an aqueous alcohol mixture in combination with water repellant compounds, hair setting compounds that may be shampoo and/or water rinse removable, or hair setting compounds that may be slowly removable by cationic shampoo but not by water rinse or ordinary anionic shampoo typically applied as a home shampoo wash of hair.

Water repellant compounds for inclusion in the topcoat composition may include waxes, silicones, organofluoride compounds such as polytetrafluoroethylene. Preferred among such repellants is carnauba wax, beeswax, olefinic wax, paraffin. Polyurethanes, polyureas, polyesters, polysilicones and combinations thereof may also constitute constituents of the topcoat composition. Preferably, these polymers have significant numbers of non-reactive functional groups distributed throughout their polymer chains and as pendant groups so that hydrogen bonding, dipolar interaction and ionic interaction with the underlying films on the hair are produced. The presence of such polymers adds water repellency, shine and reasonable buoyancy character to the hair.

Hair setting compounds for inclusion in the topcoat composition may be readily removable with ordinary shampoo washing or may be long lasting in that multiple shampoo washings slowly will remove the hair setting compounds. The hair setting compounds enable retention of a particular set or coiffure under typical environmental conditions, such as rain, humidity and wind. Nevertheless, they may be removed by shampoo washing with commercially available shampoo formulations. The hair setting compounds useful for inclusion in the topcoat composition may be copolymers of an acidic vinyl monomer such as (meth) acrylic acid, a hydrophobic nonionic vinyl monomer such as alkyl (meth)acrylates, and first and second associative monomers such as polyoxyalkyenyl fumaric or similar unsaturated dicarboxylic acids. The compounds may be polyvinylpyrrolidones (PVP), copolymers of PVP and vinyl acetate (VA), acrylate and hydroxyalkyl acrylate copolymers, CARBOPOL (polyacrylic acid), CARBOPOL ETD polymer, xanthan gum, hydrophobically modified cellulose. Still other substances useful as hair setting compounds and as repellant compounds for topcoats are based upon (meth)acrylic copolymers of (meth)acrylic esters of C6 to C20 alkyl groups and (meth)acrylic esters of unsaturated alcohols and hydrophilic monomers such as (meth)acrylic acid. Copolymers of this formulation have unsaturation sites as films applied to the hair. A short UV irradiation of such copolymers as films enables cross linking and conveys wind, rain and shampoo resistance to the topcoat composition. Block copolymers of (meth)acrylic acid, crotonic acid, alkyl (meth)acrylates and minor percentages of olefinic monomers such as styrene provide the holding, low tackiness and high humidity resistance qualities to the topcoat while at the same time enabling readily removal with shampoo washing. Incorporation into the topcoat of a non-tacky pressure sensitive adhesive such as a copolymer of butyl acrylate and methacrylic acid with the percentage of methacrylic acid being minor on the order of 2 to 4 wt % also promotes hold and set. In some instances, a topcoat formulated with (meth)acrylate copolymers that are not readily removable by shampoo washing and display thermoplastic qualities at temperatures about at least 20° C. above human body temperature may be useful for reset of hair styles. This version of the topcoat may be warmed with a warm hair dryer and the hair reset to a new style. Cooling the reset hair provides the reset hair style as the thermoplastic polymer retains the shape provided by the reset.

The topcoat composition may contain the polymer compounds as microparticles dispersed in the medium or may be dissolved in solution with the medium. The topcoat optionally may contain pigment particles and dispersant as described above. The topcoat may be applied as a liquid composition using a brush, sponge or other similar applicator to coat individual hair strands. Alternatively, the topcoat composition may be incorporated into a spray pump container and applied as an aerosol to the hair. Applied as a spray the topcoat composition preferably is formulated to remain liquid on the hair for a sufficient time to enable gentle brushing to transfer the liquid throughout the hair strands and enable essentially all hair strands to be coated. When hair styling is part of the topcoat process, the hair may be set with mechanical devices or may be set with heat and mechanical manipulation as described above.

Post Care Composition

The post care composition typically may be applied by the user periodically to preserve the shine, color lastingness and character of the color coating of the hair. The post care composition incorporates ingredients that impart lubrication, feel modifiers, sacrificial semi-fluid films to the hair. Includes are non-ionic surfactants, cationic surfactants such as long chain quaternary ammonium compounds, amosilicone conditioners, fatty acid amide conditioners, fatty alcohol betaines and sultaines, non-penetrating surfactants with a molecular volume larger than about 450 cc per mol. The post care composition may be formulated in a medium such as an aqueous or aqueous alcoholic medium that is capable of volatilization over a short period of time, such as one to five minutes. The post care composition may be applied to keratin fibers as a spray or as a liquid. Also useful as a post care composition is a protective composition that may be applied as a mask to the skin and parts of the user that are not to be treated with the compositions described herein. The protective composition forms a thin film mask on the skin and is readily removable by peeling. Adhesion to the skin is minimal so that peeling does not injure the skin. Compounds in aqueous alcohol solution provide the mask film upon evaporation of the medium. Compounds such as polymers and copolymers of high Mw organic hydroxy acids such as lactic and glycolic acid provide useful peelable masks. The post case composition can be designed to specifically care for the coating on the surface, versus the surface itself. So for example in the context of a coating on the hair surface, rather than use a regular product that is designed to clean and condition the hair surface, the post care composition is tailored to look after and care for the coating upon the hair surface.

Solids Content

Embodiments of the film forming composition and pretreatment composition include solids and liquids. The solids comprise any substance or material of these compositions that in a form uncombined with any other material, solvent, liquid or substance is has a solid physical form at ambient conditions. Included at least are the polymers, small molecules and associated catalyst/promotor materials and the pigment microparticles of these compositions. The medium, in contrast is a liquid and functions as a solvent and/or a liquid in which solid particles are dispersed. The optional components as well as the plasticizer, dispersing agent, surface treatment agent, cross linking agent and other materials added to the medium, if any, are included in the solids content as long as they remain with the polymers, reaction materials and pigment microparticles following application and setting of the color composition and pretreatment composition as a coating on strands of human hair. This includes substances that ordinarily would be regarded as liquids because they would remain in the coating on strands of hair.

The solids content of the film forming composition and pretreatment composition may range from about 0.1 wt % to about 50 wt % relative to the total weight of the respective composition. A preferred solids content ranges from about 0.1 wt % to about 20 wt % and another preferred solids content ranges from about 0.2 wt % to about 12 wt % relative to the total weight of the composition. An especially preferred solids content range is about 0.3 wt % to about 11 wt % with contents of about 1 wt %, about 2 wt %, about 3 wt %, about 4 wt %, about 5 wt %, about 6 wt %, about 7 wt % and about 8 wt % being more especially preferred.

The film forming composition includes the binder, the linker and the pigment or color bodies when the film forming composition is ready for application to keratin fibers. These three components are all solids and each constitutes a portion of the total solids content of the film forming composition ready for use. When the film forming composition is maintained separately as the binder and medium, as linker and medium and pigment and medium, the especially preferred solids content range given above is the preferred concentration of the binder in medium when stored in a separate container. The concentration of pigment in dispersant and medium in a separate container usually has a much higher concentration and in preparation for combination into the film forming composition, several of the different pigments are combined and diluted as described herein to form the coloration factor of the film forming composition. The linker is also in a low solids concentration range as described above when the linker is in storage. The linker is typically combined with the binder in medium just prior to application to keratin fibers.

The ratio of the concentration of film forming composition to pretreatment composition upon application to keratin fibers is adjusted to provide at least molar amounts to enable the small molecule and linker to inter-condense when the linker includes alkoxysilyl groups. Preferably, the molar amount of the small molecule is larger by from 2% to 20%, preferably 3% to 10%, more preferably from about 5% to about 10% relative to the molar amount of the linker. The concentrations and molar amounts designed to deliver concentrations of from 2 wt % to 4 wt % of the small molecule in the pretreatment composition and the linker in the film forming composition and preferably a molar excess of small molecule relative to the linker are calculated and measured into delivery containers so that application of a metered container of the pretreatment composition onto a portion of hair followed by application of a metered container of film forming composition onto the same portion of hair will deliver the desired results of small molecule and linker inter-condensation.

Testing the Flexibility of a Coating

With the color coating prepared on a releasable substrate and isolated as a standalone polymer film it can also be tested for optical density to check that the polymer film does not itself alter the hair appearance of the hair too significantly.

Further the polymer film preferably can be tested to reveal it's glass transition point (Tg) as described above so that it is possible to prevent the colored coating from being damaged or cracked and to secure washing and friction remanence.

The color coating can have a surface energy between about 20 and about 50 mN m⁻¹.

Ultimate elongation. The term ultimate elongation refers to the amount of elongation a given material can experience under a specific test method before failure occurs and the material breaks into more than one piece. It is the separation at break divided by the initial separation in the test, multiplied by 100 to give a percentage ultimate elongation.

Young's modulus. Young's modulus, or the Young modulus, is a mechanical property that measures the stiffness of a solid material. It defines the relationship between stress (force per unit area) and strain (proportional deformation) in a material in the linear elasticity regime of a uniaxial deformation. It is the Stress/Strain in this region.

Ultimate compression. The term ultimate compression refers to the amount of compression a given material can experience under a specific test method before failure occurs and the material breaks.

Average repeated elongation before failure. Refers to the number of elongations to a fixed level of elongation repeat cycles that can be performed on a test material before failure occurs and the material breaks into more than one piece.

The mechanical properties of the elastomer (Young's Modulus, Ultimate elongation, Ultimate compression, average repeated elongation before failure) are measured in a known manner using a Texture Analyzer TA.XT.Plus (Stable Micro Compositions).

For the Young's Modulus and Ultimate elongation, the elastomer is prepared as a continuous film, for example 10 Mil thick, on a release layer (for example baking paper) using a BYK square applicator or bird type film applicator (for example 5570 Single Bar 6″, 10 mils or 5357 or Square Frame 4″, 5-50 mils). If the elastomer is produced as a diluted composition, those skilled in the art will select the appropriate thickness of the drawdown film to produce a suitable film for testing. The film is left to cure at 25° C. for ˜24 hours or more. The elastomer is removed from the release layer and cut into rectangular sections measuring 30 mm by 10 mm using a scalpel. The thickness is then measured using a calliper to account for any shrinkage or solvent loss during curing. The rectangular film is then attached to the TA instrument within an initial separation of 12 mm. The sample is then elongated at a rate of 0.5 mm s-1 until the elastomer sample breaks. The Young's modulus is defined as the initial slope of the linear portion of the elastic region of the force-elongation curve, which occurs just after the initial force of 5 g is applied. As the initial cross-sectional area is known, the force is converted to MPa to calculate the Youngs modulus. The ultimate elongation is indicated as a percentage, i.e. extension distance at break/initial distance*100. To assess the average repeated elongation before failure, first the ultimate elongation of the sample is measured. The sample and TA instrument are arranged in the same way as to assess the ultimate elongation. The sample is then elongated at a rate of 0.5 mm s-1 to a fixed elongation of 60% of the measured ultimate elongation. The sample then returns to its original state at a rate of 0.5 mm s-1 and the cycle is repeated until the sample breaks, or until a maximum of 2000 repeat cycles.

For the Ultimate compression, the elastomer is prepared as a continuous 3 mm film on a release layer. The film is left to cure at 25° C. for ˜24 hours or longer. The elastomer is removed from the release layer and a series of cylindrical disks are punched out of the film with a 3.5 mm diameter. The thickness is then measured using a caliper to account for any shrinkage or solvent loss during curing. The rectangular film is then attached to the TA instrument using a compressive cycle. The sample is compressed at a speed of 0.05 mm s-1 until the sample breaks. This is observed as a rapid deflection within the stress strain graph during the compressive cycle and is clear to those skilled in the art. For all of the above mechanical property measurements results given are an average of at least 7 measurements.

Kits and Container

The film forming composition and the pretreatment composition may be maintained in separate storage compartments or in separate kit form especially if they will react together without special activation. Additionally, any catalyst/promotor/acid initiator for the film forming composition and/or pretreatment composition may be maintained separately so that it will avoid catalysis otherwise cause reaction of the alkoxysilyl groups. A convenient storage means can be utilized such as plastic squeeze tubes, plastic bottles, glass containers, sachets, multi-compartment containers, tottles, spottles syringes and plunger operated dispensing devices. Unit amounts for combination can be formulated so that the entire contents of a unit of the film forming composition can be combined with the entire contents of the catalyst/promotor for application to the keratin fibers. Alternatively, metered or calibrated dispensing containers for providing measured amounts of the components as directed by printed instructions can be provided. With some embodiments, these components can be pre-combined for storage and handling as long as a substantive constituent that would cause in situ linking is maintained in a separate compartment.

Use of the foregoing delivery means enables preparation of an embodiment for practice of the method of the present invention. This embodiment may comprise sequential, simultaneous or premixed application, to keratin fibers, of the pretreatment composition and the film forming composition. Pigment microparticles may be incorporated in the film forming composition. This aspect of application provides an underlayer of pretreatment composition and overlayer of film forming composition on the keratin fibers. Management of the medium removal, temperature of the applied compositions and use of activation agents, if any, will enable transformation to a color coating in which the polymers of these compositions in situ interact to covalently, hydrogen bond, electrostatically, coordinately, ionically, dipolar-wise and entanglement-wise connect as the completed color coating. For the film forming composition amine groups of the linker and the α,β-alkenoyloxy groups (Michael groups) of the binder are chemically reactive so that covalent and/or coordinate bonds are formed between molecules of linker and binder. Also, the alkoxysilyl groups of the linker when present also combine with similar groups of the small molecule of the pretreatment composition and the amine groups of the small molecule and the Michael groups of the binder react so that the linker, binder and small molecule covalently interact to bind all constituents together. With this aspect, the resulting color coating on keratin fibers provides good remanence against repeated shampooing, rinsing and contact with mild detergents, soap and similar wash substances.

The kit forms for the pretreatment and film forming compositions may also include one or more containers or package units for the materials and/or apparatuses for practice of the Praeparatur and Fundamenta techniques. A package unit for the Praeparatur technique may include one or more containers of various concentrations and kinds of anionic surfactants as well as containers for additives such as pH adjustment and carbonate solutions. An instruction packet may also be included to direct when to use the kinds of anionic surfactant, how to dilute them, how to massage and/or work the surfactant compositions throughout the anagenic hair and how to rinse away and dry the anagenic hair after the Praeparatur treatment. A package unit for the Fundament technique may include one or more containers with various concentrations of PETT formulations as well as the carbonate base additive for preparation of the PETT formulation for use. The Fundamenta package unit may also include a cold plasma pen with associated electronics and attendant wash and rinse compositions. An instruction packet may also be included to direct how to use the PETT and/or cold plasma pen and/or oxidizer.

Application of Praeparatur and Fundamenta Techniques

According to the present invention, one or both of the Praeparatur and Fundamenta techniques may be applied to keratin fibers such as anagen hair. They may be applied separately, applied to different segments of keratin fibers, may be applied sequentially and/or may be applied simultaneously. The Praeparatur technique typically may be applied first to the anagenic hair and the Fundamenta technique may be applied as needed.

The Praeparatur technique typically begins formulation of an aqueous surfactant with the preferred surfactant being an anionic sulfate surfactant. Using high shear mixing techniques and appropriate dilution steps, about 10 to 40 ml of a concentrated anionic surfactant mixture of sodium lauryl sulfate and sodium lauryl ether (PEG10) sulfate may be combined with about 150 to 200 ml of distilled water. A mimic swatch prepared as described in the experimental section may be submersed in the detersive surfactant and briskly agitated with a fine tooth comb for several minutes. If a live salon hair model is the subject of the Praeparatur technique, they may be asked to place her head over a salon wash basin. The salon operator may then first wet the model's hair with water and then apply the surfactant solution to hair and massage and lather the Praeparatur composition onto the hair and scalp. After a period of time the salon operator may then rinse the product from the hair, and optionally repeat the process again. Depending upon the salon operator's or lab technician's visual inspection and touch of the hair, the salon operator/technician may also use a fine toothed comb or pass a hand held ultrasonic device over segments of the hair treated with surfactant solution. The process is continued with optional elevation of the anionic surfactant concentration and optional pH adjustment until the operator/technician's visual inspection and touch of the hair indicates sebum, grime and minerals have been removed to expose bare hair shafts.

The Fundamenta technique may be applied separate, alone and independent from the Praeparatur technique or the two may be combined in either order. For a typical combined technique, the Fundamenta technique may be applied following the Praeparatur technique application.

To accomplish the Fundamenta technique, sections of the salon model's hair or sections of the mimic tress may be exposed to a device producing a cold (ambient temperature) plasma, for example a Relyon PZ2 Plasma Pen. A typical cold plasma generator passes a stream of air, nitrogen or oxygen through a high energy RF or EMF field to produce ions and with air and oxygen, also ozone. The stream of partially ionized gas may be directed toward the hair. The result is a “cold plasma” of partially ionized gas on the keratin fibers. The “cold plasma” may be splayed over and through segments of the Praeparatur treated hair to deep clean the surfaces of the hair strands. The cold plasma is applied at a suitable distance over a period of 1 to 5 minutes, preferably 1 to 3 minutes to provide the desired effect of deep cleansing.

In an alternate Fundamenta technique, an aqueous solution of at least 10 wt %, preferably at least 20 wt %, more preferably at least 30 wt % polyalkyl ammonium bromide such as of trimethyl cetyl ammonium bromide (CTAB) or trimethyl stearyl ammonium bromide (STAB) in either alkali at a pH of about 10 or in thiol at a pH above 7 is applied to the mimic hair tress or to sections of a salon model's hair and massaged throughout the tress or hair sections for a period of from about 5 minutes to 30 minutes, preferably 5 minutes to 10 minutes. This treatment is then rinsed with shampoo at acidic pH (with acetic acid) until the CTAB or STAB is removed.

In another alternate Fundamenta technique, a composition comprising 1.9 to 12% hydrogen peroxide is mixed with a persulfate bleaching composition which can be a powder. The mixed composition is applied to the hair for a period from about 1 minute to 120 minutes, more preferably from 3 to 40 minutes and then rinsed thoroughly from the hair. In an additional alternate Fundamenta technique, a composition comprising 1.9 to 12% hydrogen peroxide is mixed with a composition contain between 0.1 and 10% of an alkali agent chosen from monoethanolamine or ammonia and ammonium hydroxide. The mixed composition is applied to the hair for a period from about 1 minute to 120 minutes, more preferably from 3 to 40 minutes and then rinsed thoroughly from the hair.

Following practice of either or both of the Praeparatur and Fundamenta technique, the mimic swatch or salon model hair is ready for the Pretreatment step according to the invention.

Application of Pretreatment Composition

According to the present invention, application of the pretreatment composition to keratin fibers as a pretreatment after application of the Praeparatur and/or Fundamenta techniques and before application of the film forming composition is at least in part a factor for achievement of the qualities and characteristics of the color coating on keratin fibers. According to this embodiment of the method, the pretreatment is applied on or to at least a portion of the keratin fibers and preferably throughout the keratin fibers. The amine groups of the small molecule of the pretreatment composition are believed to interact by hydrogen bonding and dipolar interaction with complementary keratin protein groups on the keratin fibers. The alkoxysilyl groups of the small molecule of the pretreatment composition are believed to undergo condensation to form a silicone network. Additionally, the amine groups of small molecule are believed to undergo aza-Michael addition with the binder of the film forming composition and remaining alkoxysilyl groups of the small molecule and/or network are believed to undergo condensation with alkoxysilyl groups of the linker of the film forming composition if they are present. Ultimately, a siloxanyl polymer network intimately connected with the surfaces of the keratin fibers and interconnected with the three dimensional network of the crosslinked binder-linker is formed. It is believed that these interactions, which are believed to involve one or more of covalent, coordinate, electrostatic, ionic, dipolar and/or entanglement combinations, function as melding between and among the keratin fibers, the pigment microparticles, and the polymers of the color coating formed from the film forming composition and the pretreatment composition.

Pretreatment with the pretreatment composition may be carried out prior to application of the color composition. Pretreatment may be carried out immediately prior to application of the color composition, or at least 1 hour prior to application of the color composition, or at least 24 hours prior to application of the film forming composition, or at least 10 days prior to application of the film forming composition, or at least one month prior to application of the film forming composition. Preferably, pretreatment may be carried out immediately prior to or within a few minutes up to an hour before application of the film forming composition. Typically, the pretreatment composition is at least partially dried with optional heating to at least substantially remove or otherwise eliminate its medium. For example, excess medium from the pretreatment composition on the hair may be removed by contacting the wet coated hair with an absorbent fabric or the wet coated hair may partially dried by heating with a hair drier. Preferably, substantial removal of the medium of the pretreatment composition is accomplished before application of the film forming composition.

In one embodiment, more than one pretreatment composition may be applied to the hair. It may be that two different pretreatment compositions are applied sequentially to provide a cumulative benefit for the subsequent film forming composition, which is then applied, or it may be that two different pretreatment and optionally two different film forming compositions are applied to substantially different portions of the hair. Such a case may arise when applying to hair which has quite different properties, for example, to sections which have been pre-bleached or color, versus natural hair, or for root versus tip hair. In such cases different pretreatments may be needed to prepare all of the hair for subsequent film forming compositions. While such different pretreatment would be directed to different portions of the hair, it is likely that there would be a least some minor mixing and some areas of the hair would receive both pretreatment compositions. A third embodiment applies where a pre-treatment composition is applied to a section of the hair, for example at the roots, and the second different pretreatment composition is then applied across all of the hair.

Application of Film Forming Composition Following Pretreatment

As described above, the one or more film forming compositions may be applied to the keratin fibers in combination with the foregoing pretreatment with the pretreatment composition. Embodiments of the film forming composition as the binder and linker components may be maintained separately until use. Application of the one or more film forming compositions to pretreated keratin fibers may be preferably accomplished by sequential application to segments of the hair. Once all segments are coated with one or more wet film forming compositions, the one or more film forming compositions may be dried and/or cured to form overlaid coating layers on the keratin fibers. Alternatively, the application and subsequent drying and or curing may be performed section by section across the head. Typically, the rate of aza-Michael addition cross linking of the film forming composition and rate of drying may be pre-adjusted through medium control, pH adjustment if needed, concentration, steric interaction, temperature, and similar factors controlling reaction and/or drying rate so that a premix of the binder and linker of the film forming composition preferably will not substantially interact before the premix is applied to the keratin fibers The practice of this step with the pretreatment embodiment initially introduces the film forming composition on top of the pretreatment layer of small molecules on the keratin fibers. Because the film forming composition is in a medium, penetration, combination, mixing and/or melding of the film forming composition into the pretreatment layer will be accomplished at least in part. The penetration is believed to enable the linking among the binder and linker of the film forming composition and the small molecules of the pretreatment composition and the keratin fibers. Drying and curing of these compositions preferably occur after all compositions have been applied. In this manner, melding among all layers is best achieved.

Application of the one or more film forming compositions to keratin fibers pretreated with the pretreatment composition is preferably carried out after pretreatment. This sequence may be carried out immediately after pretreatment, or at least 1 hour after pretreatment, or at least 24 hours after pretreatment, or at least 10 days after pretreatment, or at least one month after pretreatment.

The sequential, simultaneous or premix application of the film forming composition may be applied to at least a portion of the keratin fibers or may be applied all over the keratin fibers. The portions of the film forming composition may be applied sequentially, simultaneously in a single application over all the keratin fibers or may be applied step-by-step to the keratin fibers. Applying the film forming composition in a step-by-step manner as described above, may help to ensure that the treatable portions of the keratin fibers are saturated with the combined film forming composition and pretreatment composition and may therefore provide a better coverage of the keratin fibers.

Manipulative Techniques for Application

After each application of the pretreatment composition and one or more film forming compositions have been accomplished, and the wet coated keratin fibers, e.g. treated keratin fibers, optionally rinsed, the treated keratin fibers will begin to cure. If the treated keratin fibers are heated using an elevated temperature, the aza-Michael addition curing of the binder and linker and condensation of alkoxysilyl groups to Si—O—Si groups may be accelerated. The temperature of the keratin fibers can be increased to elevated temperatures above room temperature such as 40° C. or higher, for example using a hair drier. While the keratin fibers are being heated, some form of interdigitated implement can be used to help separate portions of the keratin fibers, and especially separate hair strands from one another. Examples of interdigitated devices include a comb or a brush. The keratin fibers can be heated with a hair drier while simultaneously being combed or brushed until it is dry to the touch. Alternatively, other means can be employed to heat and separate the keratin fibers such as hair simultaneously. For example, using a combination of air movement and vibrations will accomplish distribution of the multicomponent composition throughout the strands of hair.

Operational Method for Coating Hair

The performance of operational method aspects of the present invention can be applied to keratin fibers to form a coating of the pretreatment and film forming compositions and optional topcoat composition. This aspect of the invention concerns a method for coloring keratin fibers and comprises applying embodiments of one or more pretreatment and film forming compositions for a time sufficient to deposit an effective color coating on the keratin fibers such as each keratin fiber or hair strand. A somewhat to substantially overall distribution of the coating on the length and circumference of each fiber is produced.

To accomplish this aspect, after performing the Praeparatur and/or Fundamenta techniques to prepare the keratin fibers for acceptance of the pretreatment and film forming composition, embodiments of the pretreatment and film forming compositions are applied to the keratin fibers according to the sequences described above by brushing, painting, spraying, atomizing, squeezing, printing, rubbing massaging or in some manner coating the keratin fibers such as hair strands with the embodiments. Following application of a compositional embodiment to the keratin fibers such as hair strands, the composition is set, cured, linked, coordinated and/or otherwise melded together preferably by warming with blown warm air from a hair dryer or similarly treatable to remove the medium, initiate aza-Michael addition and condensation of the alkoxysilyl groups as well as hydrogen bonding, molecular entwining and polar interactions among the binder-linker polymer, the in situ formed silicone network formed from the small molecules of the pretreatment composition and keratin fibers. The setting leaves a substantial to essentially complete overall bonding and binding among these substantive constituents of the color coating on keratin fibers.

The rate or rate of reaction for the film forming composition and pretreatment composition to cure and to bond internally and with each other is the speed at which reactants are converted into products. In the context of the film forming and pretreatment compositions forming adherent colored coatings, the rate refers to the speed at which the covalent and non-covalent bondings occur. In one embodiment it is preferred that the rate of reaction/drying is not so fast that the resulting elastomer forms before the wetting and spreading on keratinous surface can occur. If the rate of reaction/drying is too fast the resulting elastomer may not then be able to subsequently wet and spread on the hair surface, resulting in an inferior coating of the hair and one that displays less resistance to washing. In contrast, a rate of reaction/drying that is extremely slow will not enable a practical result in typical times for salon coloration treatment. In a preferred embodiment the rate of reaction/drying is slow enough such that the film forming and pretreatment compositions can wet and spread on the keratinous surface, yet also fast enough that a macroscopically continuous film on a keratinous surface is formed as the film bonds/binds covalently/non-covalently. The typical period for accomplishing continuous film formation is preferably less than 48 hours, more preferably in less than 24 hours, even more preferable in less than 12 hours, most preferable in less than 6 hours and especially most preferably in less than 30 minutes following the completion of application and under normal room temperature conditions.

The bonding and binding of the substantive constituents of pretreatment and one or more film forming compositions and the keratin fibers during application provides a color coating that resists removal by washing with dilute mixtures of soap and water or shampoo and water. Color remanence is developed so that washing with dilute aqueous soap solution or dilute aqueous shampoo will not substantially remove the coating, but the coating can be facilely removed by use of a transformation trigger. The properties of the coating include remanence, flexibility, adhesion, abrasion resistance and remanence which are due at least in part to the binding and bonding character of the substantive coating constituents including at least their intermolecular entwining, ionic and electrostatic intermolecular interaction, covalent and/or non-covalent linking, hydrogen bonding, dipole interaction and lipophilic interaction of these substantive constituents.

The pretreatment and film forming compositions and optional topcoat in accordance with the present disclosure can have a viscosity that can be controlled to enable the product to be applied to the hair using either a brush and bowl or a bottle, but with sufficient rheology such that it does not drip and run from the hair onto the face or body.

Alternatively, low viscosity formulations may be applied to the hair via a suitable application device such that it does not drip and run form the hair onto the face and body.

The pretreatment and film forming compositions and optional topcoat can be utilized in concentrated form or in serial dilutions, to provide for a consistent color results substantially along the entire length of the keratin fibers.

The aspect of coloring keratin fibers with a pretreatment and film forming composition and optional topcoat as described above includes a method for this coloring. The method comprises:

(i) applying the above-described pretreatment and film forming compositions to keratin fibers to obtain an effective, deposited coloring amount of the color composition including pigment microparticles and optional additional components; (ii) setting the pretreatment and film forming compositions by removing or otherwise eliminating the medium (e.g., by drying the composition); and. (iii) setting the interaction among the reactive constituents of the film forming and pretreatment compositions by initiating the in situ linking among these groups.

During the setting/drying step, color distribution can be facilitated by concurrently moving and/or stroking the hair with an interdigitating device. Interdigitating devices include a comb or brush. The interdigitating device needs to be pulled substantially along the hair strands from root to tip. It can be pulled through at a rate of 0.1 cm s⁻¹ to 50 cm s⁻¹ or at a rate between 0.5 cm s⁻¹ to 20 cm s⁻¹.

The pretreatment and film forming compositions and optional topcoat are applied to the keratin fibers in any suitable way including spraying the pretreatment and film forming composition, massaging the keratin fibers by hand, after applying the pretreatment and film forming composition to the hand or by combing, brushing or otherwise applying the pretreatment and film forming composition throughout the keratin fibers.

The methods by which the pretreatment and film forming compositions and optional topcoat composition described herein are applied can be modified, such that the user applies the product in one region of the hair, and then can apply a diluted version in another region of the hair. The dilution formula is specially chosen to be compatible with the colorant formulation and reduces the coloring strength, while maintaining the longevity of the color result. This can effectively be a “blank” formulation, which contains broadly the same materials as the coloring formulation, but with lower or no pigments present. When diluted the ratio of the diluent to colorant can be between about 10:1 and about 1:10, about 8:1 and about 1:2 or about 5:1 and about 1:1.

Alternatively, the amounts of pretreatment and film forming compositions and optional topcoat composition applied can be altered in different regions of the hair, for example half the product is applied in the lengths of the hair, leading to a less colorful result. The difference in amounts applied in one region of the hair versus another can be between about 4:1 and about 1:4 or about 2:1 and about 1:2.

Alternatively, a combination of this approaches may be used to deliver the target color variation.

When the foregoing techniques are not possible to be applied, rather than apply a single hair color, it may be possible to apply two or more hair colors to different regions of the hair. When this is done, the different hair colors preferably provide complimentary colors so as to develop an attractive result. The difference in colors that can be used, based on the end result on hair tresses (as described later—untreated hair tresses) are as follows. As described within the CIELCh composition:

Color 1 (LCh) versus Color 2 (LCh)

Color 1 L-15<Color 2 L<Color 1 L+15 0 or Color 1 C-10<Color 2 C<Color 1 C+10

Color 1 h-45<Color 2 h<Color 1 h+45

Those skilled in the art of color measurements will know how to interpret difference in hue angles, h, when they extend from low positive values to those near to 360 degrees due to the periodic circular nature of the hue angle.

The method for use of the pretreatment and film forming compositions and optional topcoat composition in accordance with the present invention can occur during any suitable period. The period of application can be from about 0 to 30 minutes, but in any event a period that is sufficiently long to permit the coating of pigment microparticles to coat and adhere or bind to each separate keratin fiber, substantially along the entire length of each keratin fiber. The resultant is keratin fibers having a color and permanence that is at least equivalent to the color resulting from oxidative hair color, except under much milder conditions.

The pretreatment and film forming compositions described herein can be prepared by the manufacturer as a full shade, e.g., one that is ready to apply to the hair, and then shipped as a discrete unit to the user. The user may need to re-blend the pretreatment and film forming composition prior to application to ensure that the pretreatment and film forming composition delivers the optimum performance. Such re-blending can require shaking the pretreatment and film forming composition for about 1 to about 120 seconds or from about 3 to about 60 seconds. Re-blending may also be performed by stirring the pretreatment and film forming composition prior to use. This may occur for about 1 to about 120 seconds or from about 3 to about 60 seconds. Although the pretreatment and film forming compositions according to the present invention are designed to provide stable suspensions of the pigment particles, the re-blending to agitate the microparticles and resuspend them in a substantially uniform distribution is desirable.

Multiple compositions comprising different pigments can be blended together prior to application to the keratin fibers. Such blending can be done in a manner so as to apply a plurality of complementary surface colors to the keratin fibers. Typically, a large group of different pigments with small molecule coatings and concentrated in dispersant media are provided as pre-mixes for combining with the film forming composition. The color selection program describe above will determine which selections of the different pigment concentrates will provide the desired color result for the customer's hair. The pre-mixes are metered into the film forming composition at concentrations ready for application to anagenic hair.

The pretreatment and film forming compositions can include multiple layers, involving multiple applications of at least the film forming composition following the first application of the pretreatment and film forming compositions. It may be beneficial also to periodically reapply the third component. The techniques for applying multiple layers follow the techniques described above for application of a single pretreatment and color composition.

The coating of pigment microparticles comprising at least one pigment in a coating of the substantive constituents of the pretreatment and film forming compositions can be adhered to the treatable material such as hair utilizing a coating having a total thickness at any given point along the hair fiber of less than about 5 μm, preferably less than about 2 μm as measured using a scanning electron microscope (SEM). To make such measurements, a coated hair sample can be embedded in a suitable resin, and then sectioned root to tip using techniques known to those skilled in the art of scanning electron microscopy. The thickness of the layer on the surface can then be assessed along the line of cuticles over a length of at least 100 μm. The thickness of layer is determined by averaging 10 points evenly spaced over the section of interest.

In the course of application of the pretreatment, film forming compositions and optional topcoat compositions, it is possible to dress portions of hair rather than as one whole uniform area from root to tip and across the regions of the scalp. Several nonlimiting examples help explain a few of the many possible portions of the hair. In a first example the first portion of the hair refers to the hair adjacent to the persons scalp, the so called root hair region which may extend from a few millimeters to several centimeters. In this example the second portion of the hair is not adjacent to the scalp, i.e. the area which is not within the first portion. There may be some overlap between the first and second portions, due to the limitations of physically segregating these two portions on a person's head, but the two portions are different to one another. In a second example, the first portion of the hair refers to the one whole uniform area from root to tip. In this example, the second portion of the hair is then another section of hair from root to tip. These two portions are different to one another, but have a significant area of overlap, with the second portion covering an area which may to some extent overlap with the first portion.

This understanding of the different qualities and attributes of sections of hair on a person's scalp shows that it is appropriate and preferably to apply separately pretreatment and color compositions to sections of hair strands. In addition to varying the concentration of the pigment microparticles and optional coloring agent, different shades and/or colors of pretreatment and film forming compositions can be applied to different sections of a strand of hair or a group of strands of hair. For example, the hair roots, mid sections and tips sometimes or often have different shades of color in their natural condition. This variation can be mimicked, altered or covered through use of differing shades or colors of the pretreatment and film forming compositions. Roots, for example can be covered with a lighter shade and the tips can be covered with a darker shade to produce a two tone variation of the hair. Application to the hair of a first portion of pretreatment and film forming composition followed by stripping the composition from the hair mid sections and ends followed by setting the remaining composition on the hair roots will provide a first hair color coating on the roots. The mid-sections and tips can be dipped or brush applied with a second portion of pretreatment and film forming composition to complete the two color or two tone treatment. The use of multiple pretreatment and film forming compositions to produce multiple coatings on the hair can provide overlapping, sequential or coterminous coatings on the hair according to typical and routine techniques for applying multiple versions of hair color practiced by professional hair salons.

Post Treatment

An optional post treatment composition can be applied after treating the keratin fibers with the pretreatment and film forming compositions described herein. This can be applied either directly after completion of coloring with these compositions. The post treatment can be either single application or multiple application across time. The post treatment can be used to improve one or more of: feel, resistance to shampoo/conditioner/water washing treatments, and shine of the hair. Nonlimiting examples of materials used to improve the feel are those which impart lubricity to the treatable material such as hair strands and/or help the hair strands separate during the drying steps. These materials include, for example silicone conditioners, silicone polyethers, silicone polyglucose, polyisobutene, copolymers of ethylene and propylene oxide, and commonly used cosmetic oils and waxes. Nonlimiting examples of materials used to improve shampoo wash resistance are materials which act as a ‘sacrificial layer’ for example polymeric silicones and their copolymers, silicone resins, cosmetics oils and waxes. Nonlimiting examples of materials used to improve the shine of hair (meaning a decrease of the full width at half maximum parameter of the specular reflection curve as measured by a goniophotometer) are those materials which form a smooth film above the previously applied pigment polymer composite on the hair. In general, any cosmetically known film forming material can be used, but preferred are materials such as polymeric silicones and polycationic materials.

Removal of Color Coating

Hair colorants made from the pretreatment and film forming composition are very resistant to everyday hair treatments (such as washing with shampoo, conditioner etc) can be removed via use of specifically designed “removal formulations.” These are specific chemical mixtures, described herein, and are designed to work by one or both of two broad mechanisms: cleavage of chemical bonds, either linking groups in the binder of the film forming composition and solvation of components of the colored coating.

First, the mixture can be made to be a solvent for the pigment itself. In this case, the mechanism of removal involves first dissolution of the pigment from the binding matrix, followed by removal from the hair by rinsing with water or some other carrier. In this case it is believed, whilst not being bound by theory, that the chemical nature of the pigment, even when in dissolved form, is such that there is minimal attraction/solubility in the hair matrix itself, thus allowing removal of the color.

Second, the “removal formulation” can be made such that it dissolves, weakens or chemically breaks down the polymer coating holding the pigment on the hair. In this case it is believed, whilst not being bound by theory, that the pigments embedded in the binder matrix are released due to weakening or dissolution of the coating itself and, because the coloring material is a pigment, it has minimal attraction for the hair surface and is too big to penetrate the hair, and in consequence this facilitates removal of the color.

The combination of the above mechanisms will also provide the desired result of removal of the color.

Attacking the functional group bonds of the polymer network of the coating on the treatable material such as hair can have a dramatic impact on the properties of the coating which is adhered to the surface. An agent that cleaves those bonds can act as a trigger agent to divide the polymeric network and enable surfactant and solvent to readily disperse the cleaved coating. Such agents include basic amino alcohols such as dimethylaminoethanol (dimethylethanolamine, DMEA), dimethylaminopropanol, and similar amino alkanol agents such as monoethanolamine, diethanolamine and triethanolamine. These amino alcohols can be formulated in aqueous medium to enable coating removal. Additionally, or alternatively, fatty organic acids such as dodecylbenzene sulfonic acid or oleic acid may be combined with non-aqueous medium such as a volatile hydrocarbon including but not limited to dodecane to trigger removal. These organic acids function as surfactants to lift the coating from the keratin fiber surfaces and to break the functional group bonds which cleaves the polymeric network of the coating. The concentration of the trigger agent in alcoholic medium such as methanol, ethanol or aqueous medium or in non-aqueous medium may range from about 0.1% to about 15% by weight, preferably about 0.5% to about 10% by weight, more preferably about 1% to about 7.5% by weight relative to the total weight of the removal solution.

The binder with aza-Michael links may also contain a group such as an ester, amide, urea or urethan group which can function as a cleavable linkage. This linkage is susceptible to hydrolysis and can be cleaved using basic or acid lysis. The cleavage will include a counter-nucleophile which can be water or a small molecular weight monofunctional amine or thiol.

The organic or silicone polymer having chain extensions with siloxane condensation, a strong acid such as dodecyl benzene sulfonic acid (DBSA) or a source of fluoride anion tetrabutylammonium fluoride (TBAF) in appropriate solvent as described in combination with Hansen solubility parameters including δd+δp+δh wherein δd is from 13 to 25, preferably 15-19 and δp is from 0 to 15, preferably 0 to 5 and δh is from 0 to 25, preferably 0 to 8.

Additionally, the in chain functional groups such as N-acylurea, urea, urethane, amide and/or ester can be cleaved through use of a small molecular weight monofunctional amine or thiol to attack the functional group and disrupt polymer chains.

Also, if silicone polymeric bridges are present in the silicone polymer or in the organic polymer, an organic acid (such as DBSA) may be used to de-polymerize the chain. TBAF or other organic fluoride such as Olaflur can also be used to de-polymerize the chain. It is also advantageous in all “off” techniques to employ an off reagent also has some surfactant quality.

When the pretreatment and film forming composition is applied to the hair, the multi-application process physically distributes the components to cover all of the hair. The spraying, massaging, combing and/or hand manipulating the pretreatment and film forming compositions produces the full coverage and at the same time leaves thin spots in the otherwise substantially uniform coating. This activity also will aid in the removal process.

Additionally, waxy non-reactive, non-combinable substances having melting points somewhat higher than human body temperature may be incorporated into the pretreatment composition. The concentration of waxy substance may be sufficient to enable heat disruption of the polymer film of the pretreatment layer on the keratin fibers but not enough to prevent the engagement of the polymer film properties of the pretreatment layer. By warming the hair with a hair dryer at a temperature of more than 20° C. higher than body temperature, the waxy substance may be melted at least in part so as to disrupt the color coating on the keratin fibers. Combing or brushing can remove disrupted color coating.

Alternatively, an organic solvent soluble polymer such as a cellulose derivative, including but not limited to nitrocellulose, cellulose acetate-butyrate or other solvent soluble polymer may be incorporated into the film forming composition. The amounts and concentrations of the solvent soluble polymer are sufficient to enable the polymer to form separate domains of polymer film within the coating produced from film forming compositions. Contacting such a coating with an organic solvent in aqueous medium will at least in part dissolve the solvent soluble polymer and disrupt the continuous nature of the coating layer. Combing or brushing can remove disrupted color coating.

Remanence and Treatable Material Inspection

Damage caused to the hair by application of the pretreatment and film forming composition and removal of the resulting coating can be assessed by FT-IR (Fourier Transform Infrared) method, which has been established to be suitable for studying the effects of keratin surface damage. Strassburger, J., J. Soc. Cosmet Chem., 36, 61-74 (1985); Joy, M. & Lewis, D. M., Int. J. Cosmet. Sci., 13, 249-261 (1991); Signori, V. and Lewis, D. M., Int. J. Cosmet. Sci., 19, 1-13 (1997)). In particular, these authors have shown that the method is suitable for quantifying the amount of cysteic acid. In general, the oxidation of cystine is thought to be a suitable marker by which to monitor the overall oxidation of the keratinous part of the fiber. Net, the measurement of cysteic acid units by FT-IR is commonly used.

Signori and Lewis (D. M., Int. J. Cosmet. Sci., 19, 1-13 (1997)) have shown that FT-IR using a diamond Attenuated Total Internal Reflection (ATR) cell is a sensitive and reproducible way of measuring the cysteic acid content of single fibers and bundles. Hence, the method that can be employed to measure the cysteic acid content of multiple fiber bundles and full hair switches, is based upon the FTIR diamond cell ATR method employed by Signori and Lewis (1997). The detailed description of the method for testing the different damage inhibitors follows thereafter:

A Perkin Elmer Spectrum® 1 Fourier Transform Infrared (FTIR) composition equipped with a diamond Attenuated Total Internal Reflection (ATR) cell may be used to measure the cysteic acid concentration in mammalian or synthetic hair. In this method, hair switches of various sizes and colors can be used. The switches may be platted (≈1 plait per cm) in order to minimize variations in surface area of contact between readings. The Oxidative hair Treatment Protocol described above may be repeated for 5 cycles to mimic the behavior of hair after repeated bleaching cycles. Following this treatment, four readings per switch may be taken (⅓ and ⅔s down the switch on both sides), and an average calculated. Backgrounds may be collected every 4 readings, and an ATR cell pressure of 1 N/m may be employed. The cell may be cleaned with ethanol between each reading, and a contamination check may be performed using the monitor ratio mode of the instrument. As prescribed by Signori &amp; Lewis in 1997, a normalized double derivative analysis routine may be used. The original spectra may be initially converted to absorbance, before being normalized to the 1450 cm⁻1 band (the characteristic and invariant protein CH₂ stretch). This normalized absorbance may be then twice derivatised using a 13 point averaging. The value of the 1450 cm⁻¹ normalized 2nd derivative of the absorbance at 1040 cm⁻¹ may be taken as the relative concentration of cysteic acid. This figure may be multiplied by −1×10⁻⁴ to recast it into suitable units.

When the compositions of the current invention can be applied to the hair and then removed there can be a non-significant change to the level of damage to the hair, whereas with conventional oxidative colorants there can be a large increase in the measured damage.

The instant disclosure is not limited in scope by the specific compositions and methods described herein, since these embodiments are intended as illustration of several aspects of the disclosure. Any equivalents are intended to be within the scope of this disclosure. Indeed, various modifications in addition to those shown and described herein can be within the grasp of those with ordinary skill in the art. Such modifications are also intended to fall within the scope of the appended claims.

Color Selection

Also contemplated herein are pretreatment and film forming compositions having a given color area (gamut principle described above) defined by color coordinates (a*, b*) in the color space represented by the L*a*b* color composition, which can be divided into a plurality of color areas. Each of the plurality of colors obtained from the area surrounding a given set of hair fibers is judged to belong to which color area of the colored area of a certain color. The number of colors judged for each color area is counted, and the color of the color area with the largest number of colors is selected as a representative color of the area surrounding a given set of hair fibers. The compositions are capable of delivering colors on hair (test method herein for fade) such that the results colors lie within the range of about 18<L<about 81, about −2<a<about 45, and about −13<b<about 70.

When the color is removed from the keratin fibers the waste water/composition can be treatable to remove the pigments from the waste water effluent composition. This can be achieved by filtration, or through cyclone technology, where the density differences are used to force the pigments to the settle, and the water to pass through.

Salon Demonstration Regarding Anagenic Hair

Remanent Differences Between Hair Tresses and Anagenic Hair

The following SALON example demonstrated the difference in performance observed between the lab using regular untreated and treated hair tresses and when the same products were tested within a test salon on anagenic hair on models' or panelists' heads. The following compositions were used.

Pretreatment Composition (PS1):

Concentration Material Name Supplier (w/w %) PEI¹ Epomin P-1050 Nippon Shukobai 1 (MW 70.000) Preservative Phenoxyethanol 1 Medium Water Q.S. to 100 ¹polyethyleneimine

On the tresses, the coloration products were applied using the protocols described in the following experimental sections. For the salon testing, the same protocols were applied. The compositions were not applied to the whole of the models' head, discrete strands were selected, similar in width to a hair tress upon which the product was applied. This technique enabled the use of two difference coloration products on the same panelist's head on two spatially resolved strands of hair. After the coloration product was applied and dried, a short while later the model's hair was rinsed with water and then dried again.

The color remanence was performed after 15 wash cycles on the lab tresses and after the models had performed 15 wash cycles using their regular washing and grooming habits.

Salon Experiment Number: Salon1 Salon2 Pretreatment Composition: None PS1 Coloring Composition: S1A S1A Results on lab strands Untreated Hair +++ +++ Treated Hair +++ +++ Results on anagen hair Panelist 1 0 0 Panelist 2 ++ + Panelist 3 ++ ++ Panelist 4 + + Panelist 5 ++ +

The results showed that on lab tresses, on untreated and treated hair the color remanence was very strong for both composition combinations tested, Salon1 without the pretreatment composition and Salon2 where the pretreatment composition was applied.

In contrast, on the 5 models (or panelists) within the salon test, the performance varied heavily from strong to weak. Even when the performance was strong this was an average assessment, and the results were always weak for all panelists when considering the root hair, the first few centimeters of hair adjacent to the scalp. Generally, color remanence was better on panelists with hair that had been previously lightened or bleached. Those with the least treated hair had the poorest performance.

These results from the testing on tresses and on anagenic hair on panelists of the same products highlights the considerable challenges to provide long lasting remanent colored films on the outside of the hair fibers on real consumers hair. These challenges are most noticeable on the “roots”, hair which is adjacent to the scalp.

The same results were also obtained from a similar salon test using a film forming composition of isopropanol, pigment, polysilicone with pendant α,β unsaturated carboxyl groups having a weight average molecular weight of approximately 0.5 to 0.8 KDa, a polysilicone with pendant alkyl amine groups and terminal triethoxy silyl groups having a weight average molecular weight of approximately 0.5 to 0.8 KDa, and a pretreatment composition of APTES in isopropanol, water and acetic acid.

EXPERIMENTAL SECTION Examples General

The color compositions described herein within the examples are generally applied to a hair tress. One gram of each of the pretreatment composition and/or film forming composition is applied to each gram of hair tress. The tress is placed on a flat plate or in a bowl and the pretreatment composition and/or film forming composition brushed into the hair to ensure that all of the strands look visibly coated with the composition(s). The hair tress is then dried by heating with a hair dryer while combing until it is dry to the touch and the hairs are individualized.

Preparation and Application of Film Forming Systems to Color Hair:

The compositions used herein are prepared as described in the following sections prior to starting the applications steps.

General Description of Treatment and Application of Color Composition Steps:

-   -   If required such as with mimic hair, apply at least one         Praeparatur composition to the hair tresses and then rinse the         hair strands. Repeat as required.     -   If required such as with mimic hair, perform a Fundamenta step         on the hair tresses.     -   Apply at least one Pre-treatment composition to the hair         tresses.     -   Application of film forming composition to hair tresses followed         by curing to produce colored hair tresses.

After the color composition is applied to the hair tress one of the following is then performed to assess performance:

-   -   Standard color remanence test     -   Full root simulation color remanence test     -   Color removal procedure

Standard color remanence procedure: The standard color remanence procedure is used to determine the remanence of the colored hair tresses.

-   -   1. Rinse the colored hair tress for approximately 10 seconds         with water (4 L min⁻¹) at approximately 37+/−3° C.     -   2. Apply 0.1 g “Wella Professional Brilliance Shampoo for fine         and normal hair” without dilution to the individual colored hair         tress weighing about 1 g described above.     -   3. Shampoo is worked into the colored hair tress for about 30         sec with fingers by using a stroking motion into the hair.     -   4. The shampooed colored hair tress is rinsed with water for         approximately 30 seconds.     -   5. The rinsed colored hair tress is then dried using a hot blow         dryer while mechanically separating the fibers using a comb         until uniformly dry.

Steps 1-5 described above represents one cycle of the standard color remanence procedure. Within the following experiment sections the standard remanence cycle is repeated 15 times, giving a total of 15 cycles of shampoo applications. The visual color remanence assessment, described below, is then performed to assess the color remanence after the standard color remanence test.

Full root simulation color remanence test: This test was used to determine the color remanence of the hair coated with a multicomponent coloring composition under more demanding conditions which are designed to better mimic a person's anagenic hair and especially a person's root hair. Versus the standard color remanence test three changes are made. Rather than using standard natural white hair tresses, light blonde hair tresses are used. Prior to application of a color composition (pretreatment and film forming compositions) to the tresses, a sebum mimic is applied to the tresses as described below to account for the anagenic hair with sebum. After curing to produce a colored tress, the colored tress is washed using an extended protocol including reapplication of sebum mimic to imitate the recoating of the hair with sebum originating from the sebaceous glands in-between hair washes. The full root simulation hair tress is termed mimic hair or mimic hair tress throughout this application. A synonym also used in this application to describe mimic hair is “full root simulation hair.”

The following procedure describes initial sebum application to produce mimic hair. The light blonde hair tresses (untreated tresses) are treated with synthetic sebum to better simulate root hair found on a person. Sebum measuring 0.1 g of (Hautfett nach BEY, sold by Wfk-Testgewebe GmbH) is applied to the individual hair tress weighing about 1 g described above. The tress was placed in an over at 40° C. for 30 minutes to produce a mimic hair tress.

Steps to apply the color composition (pretreatment and film forming compositions) to the mimic hair tress are performed as described above. The color coating on the mimic hair tress was then allowed to rest at 20° C. and 60-70% RH for 20 hours. This lower temperature is chosen to more closely replicate conditions on a person's hair.

Remanence Procedure for Full Root Simulation Test

After 20 hours, the following sebum and shampoo sequence was performed upon the mimic hair tress with color coating as described above.

1. Apply 0.1 g of synthetic sebum to the colored mimic hair tress weighing about 1 g described above. The sebum is rubbed into the tress to distribute it evenly. The reapplication of sebum imitates anagenic hair and its continual coating and recoating with sebum. 2. Place the tress in the oven at 40° C. for 30 min. 3. Rinse the hair tress for approximately 10 seconds with water (4 L min⁻¹) at approximately 37+/−3° C. 4. Apply 0.1 g “Wella Professional Brilliance Shampoo for fine and normal hair” without dilution to the colored mimic hair tress weighing about 1 g described above. 5. Shampoo is worked into the colored mimic hair tress for about 30 sec with fingers by using a stroking motion into the hair. 6. The shampooed colored mimic hair tress is rinsed with water for approximately 30 seconds. 7. Apply 0.1 g “Wella Professional Brilliance Shampoo for fine and normal hair” without dilution to the individual colored mimic hair tress weighing about 1 g described above. 8. Shampoo is worked into the colored mimic hair tress for about 30 sec with fingers by using a stroking motion into the hair. 9. The shampooed colored mimic hair tress is rinsed with water for approximately 30 seconds. 10. The rinsed colored mimic hair tress is then dried using a hot blow dryer while mechanically separating the fibers in the substrate material until uniformly dry.

Steps 1-10 described above represent one cycle of the full root simulation color remanence test. These are repeated for a total of 5 cycles. As in the standard color remanence test, full root test results in a total of 10 shampoo applications to the hair tress prior to assessment. The visual color remanence assessment described below is then performed to assess the color remanence after the full root simulation color remanence test.

Color Remanence Assessment

Remanence was assessed visually by comparing the washed samples versus a retained tress which had been colored but not washed. Color remanence was graded as either very strong when the color after washing was either unchanged or remaining very intense, strong where the color remained intense but was noticeably less than the starting color, moderate where the color was still visible but obviously less than the starting color or weak where none or a low level of color. To simplify the results tables shown below they were giving the following annotations, very strong=+++, strong=++ and moderate=+, weak=0.

Hair tresses used for testing. Three types of hair were used to mimic consumers hair from their tips to their roots.

-   -   Treated hair tresses. These were tresses which were subjected to         the following treatment to reflect consumers tip hair: Natural         white undamaged human hair was purchased (Kerling International         Haarfabrik GmbH, Backnang, Germany) in the form of 10 cm long         and 1 cm wide tresses. The tress was treated with a mixture of         Blondor Multi-Blonde bleach powder available from Wella         Professionals mixed 1 part with 1.5 parts of 12% Welloxon         Perfect available from Wella Professionals. About 4 g of this         mixture was applied to each gram of hair. The tresses were then         incubated in an oven at 45° C. for 30 minutes after which they         were rinsed in water, 37+−3° C. with a flow rate of 4 L/min for         2 minutes and the hair was then dried with a standard Hair dryer         from Wella.     -   Untreated hair tresses. These were used to reflect mid length         consumer hair. The Natural white undamaged human hair described         above was used as received. Additionally, in some procedure         light blonde hair was purchased (Farbe 9/0 from Kerling         International Haarfabrik GmbH, Backnang, Germany) in the form of         10 cm long, 1 cm wide strands. The light blonde hair has in         prior testing been shown to be a better mimic of consumers root         hair, the hair adjacent to the scalp. Whilst not wishing to be         bound to theory, it is thought to be less processed by the         supplier prior to preparing hair tresses than the natural white         hair tresses. These hair tresses were also used as received.     -   Mimic hair tresses These are the untreated hair tresses to which         synthetic sebum is applied and distributed throughout the hair         strands as described above in the section titled Full root         simulation color remanence test. To simulate the continued sebum         secretions of anagenic hair, the synthetic sebum composition is         reapplied to the color coated mimic hair tress after each         shampoo of the remanent testing.     -   Untreated hair tresses as purchased and as used are not coated         with natural or synthetic sebum, but they do have the F layer         coating. Mimic hair tresses are coated with synthetic sebum and         have the F layer coating as a result of the use of the untreated         hair tresses as the starting material for the mimic hair         tresses.

Color Removal Procedure

1. Apply 2 gram of color removal composition to 1 gram of colored hair tress. 2. The color removal composition is worked into the colored hair tress for approximately between 30 sec to 1 minute with fingers or a comb of manipulation instrument by using stroking motion into the hair. 3. Leave the color removal composition onto the colored hair tress for approximately 15 min unless stated differently. 4. Remove excess color removal composition with fingers first and then remove further remains with an absorbent tissue material. 5. Repeat step 1 to 4. 6. Remove excess color removal composition with fingers first and then remove further remains with an absorbent tissue material. 7. Apply 0.2 g of “Wella Professional Brilliance Shampoo for fine and normal hair” without water dilution and work into the colored hair tress for 1 minute with fingers by using stroking motion into the hair. 8. The shampooed colored hair tress is rinsed with water for 30 sec. 9. Apply 0.1 g “Wella Professional Brilliance Shampoo for fine and normal hair” and work into the colored hair tress for 30 sec with fingers by using a stroking motion into the hair. 12. The shampooed colored hair tress is rinsed with water for 30 sec. 13. The rinsed colored hair tress is then dried using a hot blow dryer until uniformly dry. 14. Comparison of the hair tress from the 2 color removal cycles to an uncolored hair tress indicates the degree of color removal.

EXAMPLES Example 1. Performance of the Film Forming Composition which has Received a Pre-Treatment Preparation Procedure for Film Forming Composition Comprising at Least Two In Situ Covalently Reactive Components and a Pigment and a Pre-Treatment.

The pigment is either combined with isopropanol and a dispersant or with isopropanol, a dispersant, silanes and an alkaliser using a speedmixer or DAC mixer. This mixture is called either pigment paste or pigment paste with silanes and contains up to 15% pigment. The two in situ covalently reactive components from the film forming system are then also added and then mixed until uniform using standard lab methods. The composition is used within 2 hours of making.

It is sold by BYK Inc. ³SCA is an acronym for trimethoxysilylpropyl diethylenetriamine

Preparation Procedure for the Pre-Treatment Compound

The separate pre-treatment compositions are prepared by combining the pre-treatment compound into a solvent such as water or isopropanol and mixing until uniform. The resulting mixture is the pre-treatment composition. The pre-treated hair tresses may be kept at rest for a time period as much as a day at 50° C. and 85% relative humidity condition and also at room temperature 20-25° C. at 50-60% relative humidity.

General Coloring Procedure: To the pre-treated hair tress described above is added a freshly prepared film forming coloring composition prepared as described above, 1 gram of composition is applied per 1 gram of hair. Application is accomplished by a slow distribution and spreading on the hair tress, for example, with fingers, brush, comb or other manipulation instrument/tool. The slow distribution can be accomplished by application with a syringe or a pipette serially to portions of the hair tress. Excess is removed with absorbent tissue material and the resulting colored hair tress is blow dried while combing using a hair dryer to achieve better hair individualization. Treated hair tresses may be kept at rest for a time period as much as a day at room temperature 20-25° C. at 50-60% relative humidity (RH).

In the following three experiments, the curing conditions used after the full coloring were room temperature 20-25° C. at 50-60% RH for 24 hours prior to performing the standard color remanence test.

In the control leg, 1A with the polyethyleneimine pre-treatment and the pigment paste with pigment red 122, the remanence was shown to be very strong on untreated hair, and on treated hair, and only a partial color removal after the color removal procedure was possible. 1B, with SCA as pre-treatment and the pigment paste with pigment red 122, provided similar to slightly inferior remanence to 1A. Very strong performance was observed on untreated and Strong performance treated hair respectively, with this time a complete color removal after the color removal procedure. 1C, which is similar to 1B except for the pigment paste, this time also containing silanes provided superior performance to the control 1A. Very strong performance was observed on both untreated and treated hair and complete color removal after the color removal procedure was possible. These results show the additional benefit of the small molecule in the pre-treatment, combined with the pigment paste prepared with additional silanes, enabling very strong color remanence and complete color removal.

Example 2. Level of Film Forming Reactive Components

The following experiments were performed to show the impact of the film forming reactive components on performance. These were performed using a pre-treatment composition and cured at 50° C. at 85% RH. The pigment paste used was the pigment paste with silanes. The curing conditions used were room temperature 20-25° C. and at 50-60% RH for 24 hours prior to performing the standard color remanence test.

These experiments were performed to understand the impact of the level of the film forming reactive components on the color remanence. All hair samples were treated with the same pre-treatment, after which the tresses were treated with a series of coloring composition 2A to 2E with increasing levels of film forming reactive component. The performance was assessed via color remanence, an additional initial assessment of the feel after coloring and the color removal performance was done. In all the experiments, the color removal was complete after having performed the color removal procedure, except for 2E, the highest level of film forming composition. The amount of material put onto hair and the hair feel could be the reason for not enabling a complete removal of the color from the tresses, due to the difficulty for the removal procedure of penetrating a thicker and more rigid film.

At the lower level of coloring composition, 2A the color remanence was weak respectively, on both untreated and treated hair. At the highest levels of film forming composition 2D-2E, the performance was also moderate on untreated hair and on treated hair. Further the initial hair feel was assessed as poor on 2D and 2E. The poor hair feel was connected with the way the hair fibers no longer moved as independent strands, but rather collectively giving the hair a rigid wooden unnatural texture. Therefore, the best performing product within this series were 2B and 2C where the performance was strong on both types of hair for 2B and very strong on untreated and treated hair respectively for 2C, indicate a preferred coloring composition level between 2.5 and 6 wt % in the film forming composition. It is understood that this level would vary with the amount of product applied to the hair, and that higher levels of film forming composition would be acceptable if less of such a product was then applied to the hair.

Example 3. Pre-Treatment Compound Level

The following experiments were performed to show the impact of the pre-treatment compound level on performance. These were performed using a series of pre-treatment compositions followed by the same film forming composition. The curing conditions used were 40° C. 95% RH for 20 hours prior to performing the standard color remanence test.

These experiments were performed to understand the impact of the level of the pre-treatment active level on performance. Hair tresses were treated with a series of pre-treatment compositions 3A-3E, after which the tresses were treated with the same film forming composition. The performance was assessed via color remanence, an additional initial assessment of the feel after coloring and the color removal performance were done. At the lower level of pre-treatment 3A, the color remanence performance was moderate on untreated hair and weak on treated hair. At the higher level tested, 3B to 3E, the color remanence performance was strong on the untreated and treated hair for the experiments 3B and 3C and very strong on both types of hair for the experiments 3D and 3E. The poor hair feel, experiment 3E, was connected with the way the hair fibers no longer moved as independent strands, but rather collectively giving the hair a rigid wooden unnatural texture.

The color removal performance was consistently complete after having performed the color removal procedure, except for experiment 3E, for which the hair feel was also assessed as poor. The amount of material put onto hair and the hair feel could be the reason for not enabling a complete removal of the color from the tresses, due to the difficulty for the removal procedure of penetrating a thicker and more rigid film.

Therefore, the best performing products within this series were 3B to 3E, indicate a preferred pre-treatment level between 0.5 and 10 wt % in the coloring composition, even if at 10% one can start observing a decrease of the hair feel performance and also of the color removal performance. One skilled in the art would understand that this level would vary with the amount of product applied to the hair, and that higher levels of binder would be acceptable if less of such a product was then applied to the hair.

Example 4. Impact of Praeparatur and Fundamenta Steps

The following examples show the impact of using a Praeparatur and a Fundamenta step when using the full root simulation color remanence protocol. For the first experiment 6A, the performance was assessed with both the standard remanence test and the full root simulation color remanence test.

Praeparatur procedure: To the hair which had a pre-treatment of sebum to replicate the hair found on a person's head, prepared using the protocol described above, either nothing was done, and the hair was then colored, or the following step was performed.

1. Rinse the hair tress for approximately 10 seconds with water (4 L min⁻¹) at approximately 37+/−3° C. 2. Apply 0.1 g “Wella System Professional Deep Cleanser Shampoo” without dilution to the individual hair tress weighing about 1 g described above. 3. Shampoo is worked into the hair tress for about 30 sec with fingers by using a stroking motion into the hair. 4. The shampooed hair tress is rinsed with water for approximately 30 seconds. 5. Apply 0.1 g “Wella System Professional Deep Cleanser Shampoo” without dilution to the individual hair tress weighing about 1 g described above. 6. Shampoo is worked into the hair tress for about 30 sec with fingers by using a stroking motion into the hair. 7. The shampooed hair tress is rinsed with water for approximately 30 seconds. 8. The rinsed hair tress is then dried using a hot blow dryer while mechanically separating the fibers in the substrate material until uniformly dry.

Fundamenta Procedures. Two different Fundamenta procedures were performed separately on the hair. In both cases, this was performed on the hair which had first had the Praeparatur step described above.

Plasma Fundamenta procedure. An atmospheric low temperature plasma pen, Piezobrush® PZ2 (Relyon Plasma, Regensburg, Germany) was used to treat the hair tress. It was held 5 mm from the tress surface and moved slowly up and down along the tress for 2 minutes on each side to perform the Fundamenta step.

Alkali cleaning Fundamenta procedure. The following solution was prepared, CTAB (trimethyl cetyl ammonium bromide) 0.20%, sodium carbonate, 1.60% and water 98.2%. 50 g of solution was prepared for each tress that was treated in a beaker. This was heated to (60° C.). The tresses were placed in the alkaline surfactant solution for (15 min) with stirring performed by a magnetic stirrer. Afterwards tresses were removed from the surfactant solution and dried. The following acidic cleaning composition was then prepared. Texapon N70 (70% in Water) 14.29%, Isopropanol 25.00%, Acetic acid 3.00%, Water 57.71%. The following steps were then performed.

1. Rinse the treated hair tresses thoroughly for 2 minutes with water (4 L min⁻¹) at approximately 37+/−3° C. 2. Apply acidic cleaning composition to hair, using 0.1 g for each gram of hair tress for 60 seconds with the finger to distributed through the hair tress. 3. Rinse the hair swatch with water for 60 sec with water (4 L min⁻¹) at approximately 37+/−3° C. 4. Repeat steps 2 and 3, two more times. 5. Blow dry tresses.

The curing conditions used are detailed in the table below and are the same for the standard color remanence test on untreated hair and for the full root simulation (mimic hair tress) color remanence test on light blonde hair.

These experiments were performed to show the difference between testing remanence on regular lab hair tresses versus a full root hair remanence simulation. In the control leg, 4A, the remanence was shown to be very strong after washing regular lab tresses. The performance of 4A dropped to weak when tested using the full root hair remanence simulation. This was comparable to observations from testing such products within salon tests where the color remanence performance was weaker on head than that observed in lab testing. Test leg 4B showed very strong performance as well as 4C and 4D showed very strong performance in the full root hair simulation showing the advantage versus 4A of a Praeparatur and/or a Fundamenta Step prior to the pre-treatment and color application steps.
